I like to make slippers for gifts for friends. I have not collected too many patterns for slippers yet, but as I find more that I like I will be adding the links here.
Snowball Slippers- very fluffy looking
Button Slippers- remind me of ballet shoes
Sarah's Simple Slippers- looks like an anklet sock
Fun Folded Toddler Slippers- I think this could be altered to make adult slippers too. Interesting technique.
Sugar and Cream Slippers- simple, elegant, and feminine
Granny Square Slippers- just what it sounds like (part of me thinks that if you sewed the opening shut it would make a good potholder too, lol)
Slipper Socks- this looks like the heel up is worked vertical. Interesting technique.
Adult Slippers- look like running shoes
Molly's Mukluks- great looking boot style slipper.
Simple Slippers- these look very tailored, like shoes almost
Crocheted Moccasin Slippers- I like the sole on these, Mark might like a pair of these
Slipper Socks Diamond Pattern- I like the diamond on top of the instep
Slipper Sox- these have a leather looking sole and sock like tops, very cozy looking
