Here is the dress that I decided to make a bracelet for...
First step is to cut a strip of fabric 3" by at least 22"
2. Turn over the right side on each end 1/2"
3. Fold the fabric with right sides together and serge or stitch along the tube
4. Turn the tube to the right side out and press
The elastic can be 1/2", 3/4" or 1" wide
Put a safety pin through on end
6. Insert the pinned elastic into the tube and slowly pull through
7. Once your elastic gets to the end of the tube pin it to secure it
