Crocodile Flower Crochet Square Pattern

Suggested Materials - 4 mm Clover Amour Crochet Hook (US G/6  UK 8) , Worsted weight yarn
Size - Using the hook and yarn specified, your square should be a nice even 12″ when you are done.  Joyce does say that she is a very tight crocheter, so your square might come out bigger!
Using a 4 mm crochet hook (US G/6 UK 8) and double knit yarn, as I have done, your finished square will be 8.5″ big IF you stop at Round 13 and leave out Rounds 14-17.  Please note that you will still need to make Rounds 18-20, which form the crocodile stitch petals. My Yarn and Colour Choices
I am using Stylecraft Special DK.
Saffron (Rounds 1-4)
Fondant (Rounds 5 and 20)
Pomegranate (Rounds 6 and 19)
Lipstick (Rounds 7, 8, and 18)
Sherbet (Rounds 9 – 13)
Meadow (Optional Round 14)
Please Note that I changed the Optional Round to Sherbet in my final afghan.
Notes - Joyce uses chain stitches to start her rounds, which is not unusual in and of itself, but they way she uses them is different than what you might be used to.  In Round 5, for example, the initial ch-2 counts as a chain stitch and a sc.

Special Stitches
Crocodile stitch – this stitch has a slightly different configuration in each of the 3 rounds it is used in.  It is explained in each of those rounds.
Bubble stitch – the bubble stitch is made slightly differently in each of Rounds 2 – 4, but consists either of a (sc, tr) or a (sc, tr, sc).

Crocodile Flower Square Photo Tutorial
Thank you very much to Joyce Lewis for giving us permission to do this photo-tutorial for her Crocodile Flower Square.  And a special thank you to Kimberly Slifer for letting me do these tutorials and for obtaining the necessary permission.
Round 1 As written. If you are not familiar with working into a magic ring, this video tutorial from Moogly is clear and easy to follow. Please remember, when working into a magic ring you HAVE to work away your initial tail very well. If you just cut it, your whole square might unravel! Stitch count: 12 dc’s – including initial ch-3
Round 2 Ch 1 and TURN so that the back of Round 1 is facing you.  This round (and the next 2) will be worked with the wrong side of the work facing you.
It is important to note that the back end of the slip stitch join looks like a stitch, although it isn’t and should not be worked into.  Whatever you decide to do, make sure that you only have 12 bubble stitches at the end of this round, not 13! Place a piece of scrap yarn over your work before making the first st of this round (Photo 1).  Make a tr in the same st as the sl st join.  You will find this stitch to the right of the stitch marker (left if you are left-handed).  See Photo 2.  Skip the back end of the sl st join (indicated with an arrow in Photo 3) and (sc, tr) in the next st  (Photo 4).  When making the bubble stitches, make sure that the treble pops out away from you. Repeat around as instructed in the pattern.  Join to the first ch with a sl st (indicated with an arrow in Photo 5 and illustrated in Photo 6). Count your bubbles! Stitch count: 12 bubbles {24 st’s}
Round 3 In this round you will be working only into the sc’s, not the tr’s!  In Photo 4 below I have marked the tr’s with outlined arrows, and the sc’s with solid arrows.  Notice that the tops of the trebles appear bigger than the tops of the sc’s. Remember that the wrong side of the work should still be facing you and the bubbles should be facing away from you! I forgot to remove the stitch marker from Round 2 before taking the first 3 photos, sorry :)  Ch 1.  Place a piece of scrap yarn over your work.  (Tr, sc) in the same st as the sl st join  (Photos 2 and 3).  *Skip the next tr (topmost right arrow in Photo 4).    (Sc, tr, sc) in the next sc (indicated with the bottom right arrow in Photo 4 and illustrated in Photos 5 and 6)* 11 times. Join to the initial ch st with a sl st.  Photo 8 shows you what the flower center should look like on the right side at this point.Stitch count: 12 bubbles  {36 st’s}
Round 4In this round you will again be working only into the sc’s, not the tr’s.  To help you identify the trebles, it is useful to know that their top loops will appear slightly larger than the tops of the sc’s.  They will also fall directly in front of a bubble stitch. Below you will find a view of the stitches from the back, which should be facing you (left), as well as a view of the stitches slightly from the top, showing the bubbles(right).
Ch 1.  Place a piece of scrap yarn over your work.  *Skip the next tr.  (Sc, tr) in the next sc (Photos 1 and 2), sc in the next sc (Photo 3)* 11 times.  Join to the initial ch st with a sl st (indicated with an arrow in Photo 5).  Fasten off and work away your tails of yarn. Photos 4 and 5 show the last bubble stitch of the round being made.
Stitch count: 12 bubbles  {36 st’s} 
This is what your flower center should look like from the right side.  Notice that the bubbles in each round fall between the bubbles of the previous round.

Round 5
From this point onwards, you will work with the right side facing you.  So turn your center so that the bubbles are all smiling at you, not at your lap.A last reminder of how to identify the trebles.  They should be directly behind each bubble stitch and their top loops will also be slightly larger than those of the sc’s.
Joyce instructs you to join your yarn by making a sl st, followed by a ch-2.  I prefer starting with a standing single crochet instead, but it is totally up to you! Join your yarn by making a standing single crochet in the first sc after any tr around (Photo 1).  Sc in the same st.  Make 2 sc’s in the next st (Photo 2). *Ch 5 (Photo 3) and sl st into the sc at the base of the ch-5, creating a ch-5 loop (indicated with an arrow in Photo 3 and illustrated in Photo 4).  Skip the next tr (Photo 5) and make 2 sc’s in each of the next 2 sc’s*. Repeat as instructed in the pattern and join to the first sc with a sl st.  Fasten off and work away your tails of yarn. Stitch count:  48 sc’s and 12 ch-5 loops
Round 6Join your yarn by making a sl st in the first sc after any ch-5 loop.  Ch 4 (counts as first tr) – see Photo 1.As written. When making the sl st into the side of the treble, insert your hook under the top 2 loops of the tr, but from the side.
I don’t really know how to explain this bit, hehe, and got all the way to Round 20 before I realized exactly where to make the sl st. If  you have difficulty making this sl st, insert your hook between the posts, or “legs” of the 2 tr’s and make a sl st around the post of the last tr instead, as I did before I realized how to do it properly (Photos 4 and 5).  In this round (and the next), it doesn’t matter which way you do it.  It will only matter when you get to the surface crochet bit in Round 18. Fasten off at the end of this round and work away your tails of yarn. Stitch count:  36 tr’s, 12 ch-3 spaces, and 12 ch-6 loops
Round 7 . As written.
The initial ch-8 counts as a (tr, ch-4).  When joining, remember to join to the fourth ch of the beginning ch-8. Stitch count: 36 tr’s, 12 ch-4 spaces, and 12 ch-6 loops . This is what you should end up with.
Round 8 - This round should preferably be done in the same colour as the previous round, as it will be visible later when adding the crocodile stitches, but I have used a new colour to better illustrate where the stitches go. If you are using the same colour, sl st into the next ch-4 space.  Ch 1 and make 4 sc’s in the same ch-4 space. If you are using a new colour, join your yarn by making a standing single crochet in any ch-4 space around.  Make 3 more sc’s into the same ch-4 space. Sc in the next tr  (Photo 1).  Ch 2 and hdc in the tr after the ch-6 loop (indicated with an arrow in Photo 2).  (2 hdc, 2 dc) in the next ch-4 space (Photo 3).  Make 3 tr’s in the next tr.  Ch 3 and make 3 tr’s in the tr after the ch-6 loop (Photo 4).  (2 dc, 2 hdc) in the next ch-4 space.  Hdc in the next tr (Photo 5).  Ch 2 and sc in the tr after the ch-6 loop (Photo 6) Repeat as instructed in the pattern and join to the first sc with a sl st. Stitch count: 96 st’s, 8 ch-2 spaces, and 4 ch-3 corner spaces {24 st’s and 2 ch-2 spaces per side}Pop the ch-6 loops to the front of your work.
Rounds 9 – 13 - As written, my beauties.  These rounds are simple sc and dc rounds.
Round 18 Now we will start adding the petals.  Brace yourself!  You will be starting with the outer round of petals, so use the same colour as you used for Round 7. In this round you will need to work into the ch-4 spaces from Round 7.  Each of these ch-4 spaces already have 4 stitches worked into them from Round 8. You will need to insert your hook between the central 2 stitches and around the ch-4 (see Photo 1). With a slip knot already on your hook, and starting between the central 2 sc’s of Round 8 on any side, insert your hook around the ch-4 from Round 7 (Photo 1).  Make 6 tr’s into the next ch-6 loop and then ch 1.  Flatten the petal and locate the stitch in Round 12 or 13 that lies behind the petal (Photo 2).  Insert your hook around the post of that stitch (Photo 3) and make a sl st.  Ch 1 and make a sc into the side of the last of the 6 tr’s you made into the ch-6 loop.  Photo 4 illustrates the hole you should make your sc into.  Photo 5 shows the sc made.  If you cannot locate this hole, which is below the top 2 loops of the tr, you can insert your hook around the post of the tr instead, but it won’t be quite as neat (Photo 6). Now make 6 more tr’s into the same ch-6 loop (Photo 7). Finish the petal by making a sc around the next ch-4 space from Round 7, again inserting your hook between the 2 central stitches (from Round 8) made into the ch-4 space (Photos 8 and 9). Repeat around and join as instructed in the pattern. When you “tack” down the corner petals, I suggest inserting your hook around the ch-3 space from Round 10, between the 2 corner sc’s from Round 11 (Photos 10 and 11). Stitch count: 12 Petals (each containing 12 tr’s) and 12 sc’s between petals
Round 19 - Use the same yarn as you used for Round 6. Join your yarn by making a sl st around any ch-3 space from Round 6, remembering to insert your hook between 2 of the tr’s from Round 7 (that you made into the ch-3 space) – see Photo 1.  Make 6 dc’s in the next ch-6 loop from Round 6.  Ch 1 (Photo 2).  “Tack the petal down by making a sl st in the sc between petals from Round 18 (indicated with an arrow in Photo 3).  Ch 1 and sc into the side (top) of the last of the 6 dc’s you made into the loop (Photo 4).  Make 6 more dc’s into the same ch-6 loop (Photo 5).  Complete the petal by making a sc around the ch-4 from Round 6, between any 2 tr’s from Round 7 (Photo 6). Repeat around and join as instructed. Stitch count: 12 Petals (each containing 12 dc’s) and 12 sc’s between petals
Round 20 - By this time you should be churning out crocodile stitches like a machine! Do this round as written. I found it hard going getting into the front vertical loops of the sc’s from Round 5, so I inserted my hook around the post of one of the sc’s instead. I have included photos, should you need some visual clues, but this round is very much like the previous 2. Stitch count: 12 Petals (each containing 10 hdc’s) and 12 sc’s between petals. 
To get my square to the same stitch count as the previous squares, I have added an optional Round 14.  I really wish this square was slightly smaller, because I love the look of the saw-tooth outer rounds on the original and would have loved to add them! source
