I uploaded my USC chart to Ravelry today, officially becoming a contributing member of the community! Yay! I haven't done anything else with said chart in a long time though. [Side Note: I stand by my assertion that it would make a lovely blanket/afghan of many squares. I'm just too lazy to do it.]
In hindsight, I hope I'm not infringing on some USC copyright of the interlocking SC image... I think it's fair use, you know, for knitting research purposes :-) That's my story and I'm sticking to it.
