This is my first time here and I just came over to post my new easy slipper pattern. What a koinkidink to find you asking for it. LOL! Here's a link to the ladies' version:
The only difference for a man is to make them longer and make the seam narrower.
These are super easy. No shaping. No circular knitting. Just K1, P2, and K2 together to decrease. Stitch them up with elastic thread and you're done.
I made my husband's first and worked harder than I needed to, but that version is still easy. I also made a pair for our daughter. That's still another variation. I'll post that one tomorrow, too.
Good luck. Let me know if you need any help. I'd also love to get some feedback on my instructions. I want to make sure they're clear and easy to follow.
