I decided to give it a go. =)
I used one strand of Lion Brand's Jiffy with an I hook. So soft. So fuzzy. It took about a half hour all together. =)
I used chains instead of a strap so I could tie them into a bow. =]
(they look like they are all hanging open at the top, but they aren't. It's just the way my feet were squished together.)
My aunt saw them and wants a pair with a sole on them so she can wear them to work. =] Now, to find some soles...
