20 years ago, I had a pattern from a booklet called "Baby's Best to Knit and Crochet". It was a rainbow pastel ripple afghan that started as a granny square and then ripples were created along one side, then by filling in the ripple side, the ripples were continued in another direction. If anyone has this pattern, I would appreciate a copy, I have been looking for it ever since I left it in a waiting room 20 years ago with no luck.
