I made these for my Niece's 3rd birthday last week.
They are three different colours of pink netting cut in a wing shape (and sparkle added with some glitter glue!), pleated and then sewn together. I then made two covers out of fabric for the front and back and sandwiched the wings and a piece of elastic (in a figure 8 shape) between the covers. Top stitched around the covers to join it all together and presto - fairy wings!
I hope she has many adventures with them!!
