These slippers went a different direction from what I envisioned when I first started this project, and I love love love them.
They're almost entirely thrifted: the soles came from an old fake leather purse, the black wool from wool pants, the red wool from a felted sweater, and I found the buttons at a thrift store, too. The only thing that wasn't thrifted was the red lining-- it came from some solid colored cotton I had left over from making super hero capes.
Unfortunately for me, they're a little too small (probably better for a size 8 than my 9.5s). Looks like they're going to the gift closet to await the birthday of someone with appropriately sized feet...
And luckily for you, that means that I'll have to make another pair for myself. Translation: opportunity for a tutorial. But it's going to have to wait until after the New Year, cause I'm up to my neck in unfinished Christmas gift projects.
