This yarn is much more friendly with garter than ribbing.

I think these are going to be awesome slippers!

I am holding the yarn doubled for this project.

I wear US Women’s size 10 1/2 shoes, and these had plenty of stretch to fit my feet comfortably.

I hope they fit the recipient comfortably, her feet are smaller than mine.

These are just under 10 inches long, unstretched, and 4 inches deep. With this yarn, held double.
