Bamboo Stitch Beanie - free pattern &video

Patons Silk Bamboo (DK weight, 70% Bamboo 
30% Silk, 102 yds/2.3 oz per skein) – 1 skein Sea (MC), 1 skein Sapphire (CC) 
US J (6.00mm) double-ended hook
Tapestry needle 
Gauge: not especially important, and will be determined by yarn and hook choice. 
tfs = Tunisian full stitch (insert hook in space between vertical bars and draw up loop) 
y/o = yarn over (increase made) 
sl st = slip stitch 
ch = chain 
Special Stitch: 
Bamboo stitch = y/o, tfs in each of next 2 spaces, pull last two loops on hook back through y/o, at the same time.  
Any yarn/hook combination can be used with this pattern.
All return rows are as normal: ch 1 for first stitch, y/o and pull through 2 loops for all subsequent stitches
All stitches are created knitwise, meaning the hook is inserted from front to back, through the fabric.
This pattern can be made in 2 colors, as shown, or using one color throughout.
Pictured hat is made extra long for slouchy look, but can also be worn with a fold-up brim. Note that the bamboo stitch is not very stretchy. It is recommended that a test swatch be done in desired yarn.
Ch 75 (or any odd number of stitches, enough to loosely fit around your head). Join with a sl st to first ch. Do not twist chain. 
Row 1: Pull up loop in the back hump of each ch around. 
Row 2: Work bamboo stitch pattern 
Repeat Row 2 until desired length is reached. Hat pictured is 9” tall. 
Pull the last CC stitch through final forward pass stitch. Cut both yarns, leaving about a 10” tail of CC. Thread CC through tapestry needle, weave in and out of the topmost stitches, pull tight to gather the top of the hat, and secure the yarn. Weave in ends.
