I needed a new pair of slippers super fast so I decided not to dig out my Mary Jane slipper pattern but instead, use a simpler, elastic style. Prudent Baby has some great directions on how to put your slippers together.
I used an old sweatshirt for mine and used plain sweatshirt for all the pieces, even the “batting”. The bottoms will probably wear out pretty fast because of that but I wanted something especially snuggly. 😉
These can be made for just the cost of your thread and two pieces of elastic(about $.15)as well as about 30 minutes of time.
