Cut a piece of fabric with your scissors or rotary cutter that is 22" x 4.5". Fold over the top 1/2" of your rectangle and iron the edge flat.
It's an optional step, but when using silky or satin fabric I like to add some fray check glue to the edges to keep it from unraveling while sewing or wearing, so that's why the cut edges look a little darker in the photos.
Fold your rectangle lengthwise, right sides together, and sew down the length of the tube, leaving a 2" opening for turning the scrunchie later.
Now we are going to pull one end of the tube halfway through until the opening on one side meets up with the opening on the other side. Pin the openings flush with each other.
Sew around the opening with 1/4" seam allowance, sewing the two openings together.
To turn your scrunchie right side out, find the 2" gap that you left in your side seam.
Pull your material through the gap so the scrunchie is right side out. Cut a 7" long piece of elastic and pin a safety pin through one end of the elastic.
Use the safety pin end and thread the elastic through your scrunchie tube. Overlap each 1/2” end to complete the elastic circle and pin, then sew in place.
Once your elastic is in place, push it back into the tube of your scrunchie and sew the opening closed by hand. Now your oversized scrunchie is ready to use!
