I finished this popcorn granny square lapghan a few nights ago. It originally started out as a baby blanket, but I like it so much I'm going to be selfish and keep it for myself as a lapghan.
I used 2 and 1/2 skeins of Red Heart Super Saver Ombre yarn in the color 'scuba'.
I have to be honest and say that I will most likely never make another one. Those popcorns just take too long to crochet. Although making smaller squares would be ok. I'll think on that. :)
