- Iron pieces of blue and yellow fabric to some Wonder Under, following Wonder Under instructions.
- Draw the shapes of the snitch and its wings onto the paper backing.
- Cut them out.
- Peel off the paper backing and iron the shapes onto your shirt, following the Wonder Under instructions.
- Now sew around the edges of your snitch with a straight stitch.
- Put some Fray Check right on your stitches so it doesn't fray too much in the wash (this step is optional).
