Jenny Doan has a YouTube tutorial on a king size quilt. The blocks are something like 16". It's called Big Star quilt. My dear friend made one and it's beautiful! It's not hard to make. The pattern is in her magazine called 'Quilting Quickly' also, but she tells you everything about it in her YouTube video. It's a lovely quilt and easy enough for a beginner but looks like it was hard to make!
