Sometimes I am asked how I attached the handles you see above onto bags. These handles are just "rings" and the process it not too hard. If you watch my "Earflaps On A Loom" video that is the start of attaching the handles.
First, you want to create two "tabs" (aka earflaps) on each side of the loom (directly across from each other), whether a circle or straight loom. Width of tabs is up to you.
