I love the planning, designing, the cutting out of the fabric. That is by far my favorite part of quilt making. As far as the "yucky" part, I guess it would be when I lose enthusiasm for the project because the sewing of the blocks takes too long. Once the blocks are done, I enjoy putting everything together. The qulting is a challenge for me, but I do enjoy it, especially when I do a good job, which happens from time to time = )
