A few years ago, I did a quilt with 2" squares. Sorted them by color. Had a simple shape/design on a grid - maybe like a counted cross stitch pattern. Got iron-on interfacing with a 2" grid and laid the fabric squares on the grid following the design/colors, pressed them down and then folded and stitched on each vertical line. Then clipped this fold on each intersection of the horizontal lines, folded and stitched the horizontal seams. I think directions for this technique are likely out there on the internet. Lots of fun and a 'complicated' pattern is made easy.
