They are three different books by the same author, Laurie Hird. The first one is letters from farmers wives from the 1920s; the second book FWS Pony Club is letters from children trying to win a pony from the local newspaper; the third FWS 1930s is again letters from farmers wives from the 1930s. All have different blocks set beside the letters, the first and third are 6" finished, Pony Club 9" finished. All have a CD to print out the patterns for rotary cutting, template piecing, or paper piecing.
The letters are very interesting (especially to this city girl). I did the first 2 and am now doing the 3rd with a group here on QB. I've become a much better quilter/piecer since doing these--they really do build your skills.
