Hi amber

you have a top frill, piece 5 and a bottom frill piece 4, piece 3 is the actual sleeve, so the bottom frill gets sewn on to the lower edge of piece 3 and the top frill is laid on the top of piece 3 (so when you sew the binding on you are sewing through the piece 3 and the top frill)

If i get a minute I'll try to take a photo of one that I've done
You are right, I struggled with the directions for a biut too-one of those that would have worked better with diagrams!
