First, cut your piece of fabric out..
Iron on your interfacing…(obviously mine wasn’t exact, it doesn’t need to be, just close enough)
Then, I serged (or you could zig zag stitch), each short end.
Folded it over, towards the wrong side of the fabric, and ironed it.
Then, I folded it in half lengthwise like so, (right sides together) and serged down the edge…making sure to keep the ironed edges tucked down.
Then I used a safety pin to turn it right side out and ironed it.
I then sewed pleats into the fabric by folding it under every inch or so, and sewed them down. Similar to this shirt. Only I pleated all one direction.
I also dabbed a little bit of fabric glue between the fabric on the short ends to keep them closed.
I then cut a piece of felt to fit, rounded the edges…
and, sandwiching the elastic between the felt and your pleated fabric, I glued it together like so.
Then I also glued on some flat backed pearl beads for some extra glamour!
tada! I think it turned out pretty cute.
