Indian Summer is indeed much easier than the other JN patterns. It's the one I started with too. It's the quilt I cuddle under while watching TV (red flannel on the back).
I didn't understand the comment about trimming. With the JN patterns you cut pieces that are about the right size. For each piece to be added to the block, you line the edge up with the edge of another piece that's already been sewn and trimmed, sew it onto the paper, press open, and then trim the next edge to be sewn. Everything gets trimmed that way. The add-a-quarter ruler is really helpful.
