I thought I had enough of the dark teal yarn for one more square, but I was wrong. I got half way through this square yesterday and ran out of yarn just as my first seminar was ending. Sad. Since this is all scrappy anyway, I think I'm just going to connect up another color and finish the square rather than ripping it out.
This thing is about 20" by 26" right now. I think I can get at least one more row out of the remaining yarn. I'm interested to see how close to square I can get it.
