This book contains a large number of blocks that you can make with set L or set M. The 5-patch blocks of set M and the 7-patch blocks of set L produce 12 inch blocks, but by interchanging the sets, or set the blocks on point, you can also make blocks of 8.5, 16.75, 17 and 23.75 inch.
With the new set S you can make these blocks in 6 inch. Great for blocks from books such as the Farmer's Wife Sampler Quilt or Sylvia's Bridal Sampler.
