Anyone have a Slipper Pattern? (not knitted)

I'm looking for a pattern for a pair of slippers, I always have trouble finding a decent pair and dislike having hard soles for around the house (comfort rather than anything else) I had a wonderful pair I bought in the US that eventually, after a long and useful life on my feet, ended up being a small home for some very young ducklings. They were made from 3 pieces of sheepskin and while I found something similar today, the woman at the checkout managed to draw on them so I refused to buy them ( they weren't even going to off a discount!). I'd love to make something similar, they were an ankle boot kind.

I can only knit holes so does anyone have a pattern for cloth type slippers?
