Eye spy quilts can be made without cutting your squares down. Also, you can put 2 together, right sides facing, draw a diagonal line, stitch on each side of the line, cut them apart on the drawn line and make pinwheels, or, there are Tons of layouts for using half square triangles. Snowball blocks are another option.... There are so many... Any ' charm square/Nickle quilt ' pattern can be used... You would just be using 6" instead of 5" squares.
