ROUND 1: Chain 5 and make a ss into the 1st chain to form a loop.
ROUND 2: Chain 3 and make 2tr's into loop, 1 ch, (3tr into loop, 1ch) 4 times, ss to top of starting chain.
ROUND 3: ss into next tr, *(2tr, 1dtr, 3ch, 1dtr, 2tr) into next ch sp, ss into the middle tr of next group of 3*, repeat from * to * 5 times.
That's it!
I started making my titchy stars with crochet thread, but you can use any yarn and hook size you like. Quite like the rounded off style of the corners but of course you could also pin them out and make them nice and pointy too. Just give them a spray of water to make them keep their shape. Or, if you want them nice and stiff to hang up on the tree, try spray starch, or better still, paint their backs with pva (white) glue.
