Here is a tutorial for making my butterfly magnets. I have them on my online site and I was asked if I would show how I make them. You can use them for magnets or you can use them to applique to a background square for a quilt block.
I draw my own designs and I want to show you how to draw a butterfly wing. It is really easy.
Just draw a half circle. Then draw a squiggly line from one corner to the other. Don't make the squiggly line too full of hills or it will be too hard to sew later on. A nice gentle line with a couple or three hills will work well.
Then cut out the wing and lay it on cardboard. Trace around it and then cut out the cardboard wing for a template.
