I did not actually design these slippers. For as long as I or anyone in my family can remember, my Grammy was making these for everyone she knew. They were the first non-scarf project I ever knit, and I have only written down the pattern (with a couple of modifications) and offered picture tutorials where I thought they might be helpful.
The tutorials include the two-color cast on, seaming Garter side edges and cast on/bind off edges.
