Asking around on the #ravelry channel, I got a suggestion of the Sunny Spread. I haven't done crochet in a while, and that looked like a good use of the yarn. Once I got started, I realized that duh, crochet uses about 3 times as much yarn as knitting for the same space. This is good. I can get 5 squares out of one 50g ball of yarn, plus a bit extra which will be used for seaming. I'm currently planning on either a 9 x 11 blanket, or a 10 x 10, depending on if I need the extra yarn from the 100th square for seaming.
I am planning on buying a couple balls of another color for the outer border, however, as I think it'd set off the green better. I have made an exception in my diet that I can get yarn to finish a project that uses stash, as long as there's more stash than new yarn. I'll try not to abuse that too often, though. I already got 400g of Knit Picks yarn for my argyle socks, which I'll talk about in a later post.
I've 6 squares crocheted so far, it's a very easily memorized pattern:
