A friend showed me her wool applique sampler of leaves from a class she took from Sue Spargo. I just loved it and decided I needed to try some wool applique. I love working with wool anyway. I'm cutting the shapes freehand. If I'm not sure, I'll cut the shape in scrap paper first.
This is my favorite. The threads are floss, perle cotton, wool, anything in the right color. Each is a 7" square and will go in a book.
