Part of my Christmas presents from my husband was a slipper kit. It came with slipper bottoms and a gift card to my LYS so I could knit myself up a pair of felted clog slippers (cuz I made a pair for him and he loves them so much).
So I finished up a couple of projects and then went to the LYS and picked up some Cascade 220, and then a little while later I whipped them up.
I then felted them and tried them for a while
I then decided I needed to felt them a tiny bit more, and then, true to his word, he sewed the bottoms on for me (knitting my own slippers - okay... sewing them on - ulgh). I've now been walking around with warm feet...
...now just to make new ones for the girls (well, maybe in the fall... and the boy will need a pair by then too)
