The first thing that I would
recommend that you do, is go to the Paper
Piecing Practice Page. When you feel comfy with paper
piecing, come on back and try a Butterfly! You will need to print
out one copy of each of the seven units needed per block you want to
make on very lightweight paper. I suggest that you leave the
paper on the units until the whole block is pieced, for stability.
:o) A Fat Quarter of each fabric should be plenty!
