Using Adult Socks!
What you will need
1 pair adult socks (I used size 10-13)
How to do this project
Cut the ends of both socks
Cut the bottom part of the sock until the middle of the heel. Then, turn one sock inside out and put the right side out sock inside the other one.
Pin around the edges like in the video below and sew where you pinned.
Pin the elastic inside the waist part and sew it. This part is tricky because you have to stretch the elastic way more than you stretch the fabric. Mine did not come perfectly. It's really tricky!
Once the elastic is secure in place, turn the waist around the elastic and using a zigzag, sew the end of the elastic to make it look better :)
