Thank you for explaining Kathy, there is no way I could have explained that and made sense! I chain 3 or 4 sets of triangles at a time. I just make sure each set is not like the others so I can tell really quick if I picked up the wrong one.
Adrianlee, I think I used 8 yards on this one. I always buy extra because there is alway an ugly block or two. This one is not quite a full twin size. Oh and the repeat was 12 inches if I remember right.
I have seen a link showing these going together but the pattern isn't online anywhere. I will try to find it tomorrow. I normally can't work from a book either but when the class was cancelled indefinitely and I had already bought my fabric for a new grand baby, I had no choice but to sit down and go step by step. I was really surprised that it worked!
Thanks again for all the nice comments, you guys are the best!
