I'm having a hard time choosing just one part. I like putting those new fabrics in the washer, pressing and starching them, and cutting the pieces. I might like those parts best because I wouldn't have made any mistakes at those points! But it's so rewarding to start making that first seam, which fills me with hope and the expectation of what that first block will look like when finished. The quilting is nearly always a challenge as far as choosing how to quilt and what color thread to use, but so much fun once I start. Those last stitches of binding are full of anticipation for me as I await the first glimpse of the finished product and result of all that work.
