they look very good. i did notice a few places that could be alittle 'smoother' but they are great the way they are. are you using a round toothpick to help (roll the edge under and keep everything smooth?) a toothpick helps you get those nice smooth turns, curves, edges. if you have not tried this before and are not sure what i mean you can visit the PIECE OF CAKE quilt shop..they teach 'Applique the Piece of Cake Way' and have good free content on the web site.
i love your flowers! i love applique!
