Is there any butterfly without antennea??? I did it with running stitch and french knots. To make french knots, I used two plies of thread and twisted 5 times. At last, I added flat type sequins on the wings :))
I added bugles to form the bodies of the butterflies.
I wanted to create small butterflies on the "butterfly" theme block. I thought that organdy will be a good choice to create sheer butterfly wings. I made loop stitches to form wings.
