Any...
If you use a different yarn than Noro Silk Garden Sock, just chain as many stitches (multiple of 4 + 2) to make a 12in long chain.
This is a project that a beginner can tackle. The final result is a rectangle of 12 in by 25 in. I used a somewhat light weight yarn (Noro Silk Garden), with a 3.75mm hook, but you can use any hook and yarn.
The diagram would be something like:
o: Chain
-: Single Crochet
|: Double Crochet
--oo--oo-- Row 1
||oo||oo|| Row 2
--oo--oo-- Row 1

--oo--oo-- Row 1
oooooooooo Chains
