From the pictures of the various blocks, it looks like most of these blocks are well-known blocks -- 9-patch, friendshp star, bow tie, Jacob's ladder, pinwheels, oak leaf, monkey wrench/churn dash. All of these can be pieced without templates. I'm sure you could find the pattern for most of these blocks in Quilter's Cache Most of the blocks are made up of half-square triangles, quarter-square triangles and four-patches.
