Fast Forward is a great project to use pre-cut 2.5" strips. For the best effect, the background fabric should have a high contrast with the 2.5" strips. The spiraling columns will appear to float on top! The pattern has instructions for 5 sizes: Baby 42in x 42in, Youth 48in x 54in, Lap 57in x 72in, Twin 68in x 90in & Queen-King 102in x 102in. Pattern uses Creative Grids Lazy Angle Ruler CGR3754.
