your tube. set it aside and make the loop.
this picture shows the body and the small loop, before they turn into loops. the seam is ironed flat in the middle.
for the loop, you’re basically going to do the exact same thing as the main body, except with a much smaller piece of fabric.
1. cut the fabric to 3″ x 2″. with a 1/4″ seam allowance, this should give me a loop that is 3/4″ in width (subtract 1/2″ from 2″, then divide by 2).
2. sew the loop together with a 1/4″ allowance on the short side as well, but you can make this tighter or looser depending on the fabric
