Fabric Requirements

  Lap (52" x 70") Queen (88" x 105")
Light 2 yards 4 yards
Dark 2 yards 4 yards
Border 1 3/4 yard 5/8 yards
Border 2 1-1/8 yards 1-5/8 yards
Border 3   2/3 yard

The light/dark fabric should have good contrast, and should not be large scale prints. 

Border 1 of the lap size could be either the light or dark fabric, repeated. 
Border 2 (of both sizes) could be a large scale print that coordinates with the light and dark fabrics.
Border 3 of the queen size could be either the light or dark fabric, repeated.
