Kemo's mamma --
They are sweatshirt material with velcro straps that wrap around the ankle to keep them on. They also have non-skid bottoms and I sewed a ribbon with daisies to the velcro so they would be pretty. I made them using this basic pattern (but as per usual, had to alter it quite a bit to get them to fit):

I'm actually still working on perfecting them. Daisy figured out how to undo the velcro in no time flat. I tried snaps and hook & eye closures, but she figured them out too. She's too smart.
