I never knew sewing a patch could be so much fun!
Thanks to pinterest I was inspired by this post to turn the hole in my son's jeans into a vampire monster (he's really into vampires these days).
I backed the hole with red pile fabric sewn on by hand with embroidery thread. I then set about hand stitching the eyes and teeth with embroidery thread.
Not confident in the strength of my sewing, I backed the whole thing with a square of fabric cut from an old pair of jeans attached with Peel n Stick fabric adhesive.
Several washings and so far so good.
I'm kind of hoping the other knee will rip soon so I can make monster #2.
