I love Marcia Hohn's site The Quilterscache. I have spent hours searching the block patterns, sometimes hunting for a specific block or just browsing.
One of my favorites is the Depression Block:
I have hopes of one day making a gorgeous scrap quilt with this block.
I have such an affinity for Half Square Triangle quilts. I have a Fat Quarter Bundle of Anna Maria Horner's Little Folks Voile waiting for me to cut up and make a fantastic quilt- inspired by Megan at http://lucyandnorman.blogspot.com/2010/06/little-folks-quilt-love.html
What's not to love?
