Iam not sure if this link has been shared, while Iam patiently waiting for my sock yarn to arrive, I found this list of a zillion different sock/slipper patterns.
Thought I would share.
I’ve been to this link before just by coincedence, but I’m sure other passerbys thank you 
It’s a good list!
That is a great list, thanks! 
Emerald, make sure you add that to the sticky thread for fav free pattern links, above in this forum! GREAT link!
