Crochet slippers w/felted soles?

Anyone have a pattern for easy crochet slipper pattern using pre-felted material cut to shape for the sole?

I see lots of crochet slippers over on Ravalry. You could cut a sole out of felt and stitch it over the sole. Or were you thinking of something else, maybe a pattern that incorporated the felted sole into the crocheted upper?

Closest thing I’ve seen was a pattern for felted bunny slippers that was in an email I got from… probably Paradise Fibers or (I can’t remember and I deleted it already.) Complete with faces (and ears). I think it was knit though.
