Warm Winter Wishes is a project from the Stitching Among Friends group.  The kit includes all of the cotton fabric and wool for the 12" x 12" block.  If you order the Valdani (size 12) thread kit, you get a discount! 
 
Have you tried the Bloc Loc rulers? I use them in almost every quilt I make, and just love them.  For these blocks, I used the Flying Geese 1" x 2" and the Half Square Triangle - any size from 2 1/2" - 6 1/2" will work.  These are NOT required, just recommended, because they are so helpful!
