Saw a wavy quilt on the QB a couple of weeks ago & wanted to have a go at making one myself. It's a good way of using stash!!
It was fairly easy using the Creative grids curves for squares 6" x 24" ruler.
Squares can be cut from 5" to 10". Each cut square being 1" less when sewn together.
It's abit like sewing a Drunkards path pattern.
Creative grids video demo's show what can be achieved when using this ruler.
