This is how I make a red-and-white quilt. Two colors, but not two fabrics… I just don’t have it in me.
The good news is that there aren’t any limits with this block. It looks just as nice using a very scrappy assortment of fabrics in a random placement. Or use one color for all the half-triangle squares and another for the squares. Or each little quarter-block could be made with a single fabric – you’ll need 1 ¼ charm squares of 36 fabrics to make that. And that’s just the prints! Finished size 36in x 36in.
