This quilt was a great success at Festival of Quilts and this is the "How To" for the blocks.. The original quilt was made in Oakshott Air (sorry, no longer available) The tutorial is shown in Oakshott Fabrics Ruby selection. Here's the original..
I started with 1/8 metre cuts as shown. If you wish to make the maximum number of blocks from your selection, cut the eighth pieces as shown, making squares of half the width and cutting some 1 inch strips for the crosses..
Lay one of the strips on top of a square as shown, and cut the two layers together into a gentle curve
