Since you've head me talk about this pattern twice now, I'll just say that I completed the bag with 12 rows in the last step before the decreases when 14 g of yarn remained.
This project was one of the last ones I wanted to complete before I packed up and moved away from Evanston, IL. Somehow, no matter how many rows I add before starting the decreases I end up with 5 g of yarn left over! This is enough yarn for a hexipuff... (another project that I've let hibernate for way too long.)
I love this pattern so much that I have to really hold myself back to not buy more skeins of Kroy Sock FX! I have to keep reminding myself that I'm trying to solve my stash problem, not make things worse. I do have other yarns in my stash that would work great with this pattern so I have a feeling that I will be making more of these crochet market bags coming up.
