- one 2.5" square and one 2.5"x4.5" rectangle, of each of 4 colours
- four 2.5" squares background
Sew the 2.5" squares of colours into a 4-patch for the center of the block.
Add the appropriate coloured rectangle to 2 opposite sides of that 4-patch, to create the center strip of the block.
Block should be set on point, for a true card trick look.
