Step 1: Prepare Materials
First I cut the sweater remnant down the middle. You should also separate the sweater where the shoulder part is connected. Then I flipped one half to match up with the lines and curves of the other piece to make it longer and pinned it together. Be careful to try and match any stripes up and pin it in a way that will make a nice tube shape when you sew it together.
B: If you are using a single piece of fabric it should be approximately 37cm X 175cm in size. (15 in X 70 in)
Both A and B people will need to have some kind of stuffing for the middle of the tubes, preferably batting (the stuff that goes inside a quilt).
Step 2: Sew Pieces Together
After you have sewn the two pieces together sew down the middle twice making parallel lines with about 1cm or 1/4 inch in between. Then cut between the parallel lines to create two tubes. Turn them right-side out.
B: If you are working with one piece of long fabric, all you have to do is sew along one edge and turn it right-side out.
