I just used up a box of 2 1/2" squares.... Started out making scrappy 4-patches (light to dark was my only "rule")....The 4-patches grew into blocks made up of a total of 16 4-patches. I decided to make a "stress-free" quilt, nothing fancy, quilt as you go, stitched in the ditch... To make a long story short, I now have a queen-size quilt, full of color!! It's been a lot of fun, just "playing" with those little squares!!
