The first square, still with the autumn colors, is a design by Aurora Suominen. Here is her page on Ravelry.com. I'm also a member of her yahoo group, Crochet In Common. The flower in the middle part took me a little while to figure out, but after I did it went very quickly.
This crazy colored square is from "99 Granny Squares to Crochet", a book that I reported on yesterday, and one that I'll be working my way through for a while.
You know, I've always avoided designs with popcorn stitches in them, because I can't make heads or tails of the directions for making them. And since the thing I like the best about this 365 squares challenge is that I learn or at least sharpen skills, I set out to make sense of it. I'm very definitely a 'learn by watching' kind of person, so I looked up a tutorial on making popcorn stitches on Youtube. That's all I needed, apparently, because it all makes sense to me now. I can hardly wait to go back to some of the squares I've passed on because of those stitches...
