Edie,

Welcome!

I did a Google image search and am sorry to say I can't find anything beyond this picture. I'm not even sure where the graph is being sold or given away; as you undoubtedly know, Pinterest is completely unhelpful. I saw the same picture labeled as cross stitch and c2c, but if anything it actually looks like it would work better for regular crochet or knitting.

I'm sorry that's not much help. Sometimes patterns you really want to make appear, and trying to hunt them down is maddening. I've been there before and it's sooo discouraging.

Best of luck and I hope you can get something you like.
