There are books available. OBW, Stack & Whack, 4 Patch Posies all have the same basic idea with different degrees of difficulty. Every fabric has a repeated pattern as it is printed. You find a fabric with a repeat that will work and cut and stack the fabric repeat and cut your pieces. Cutebun did a great tutorial on OBW to follow. You can also search under 4PPposies for pictures. The 4PPosies I think is the easiest for a beginner to try because it is stacking 4 pieces of fabric and cutting 4 squares to make a block.
