I am starting #4 (Peacock), #1 my avatar (Butterflies), #2 just finished binding (Candlelight), #3 last wk finish hand work (Calla Lilies). Depending upon the pattern choice, is to how hard/easy. If I was to rate the ones that I am doing or have done (easy to hard) ~ Calla Lilies, Candlelight, Butterflies, Peacock. It depends upon the details, sharp curves, and points. I have only done mine with hand applique (reverse applique), but the pattern offers different methods in the directions.
