My suggestion is a 9 patch set on point --- I like to use the same solid color in the center of each 9 patch and then use it again for the setting triangles and to use white for the setting squares. Using the same fabric in the center of the 9 patch and repeating it for the setting triangles gives the quilt a unified look.....not so random...... I made one in this manner using a bunch of 30's repo fabrics that were cut 2 inches square -- it looked fabulous.
