I had rotator cuff surgery 2 years ago and after shoulder surgery you will probably need to use the one that they will provide....If it does not support your shoulder just right you will be in horrific pain....
For one to use now, go to a pharmacy and ask to look at one that would be used after your surgery...I understand what Sharon is describing, but it may help to see one up close for your self. They are very simple in their design all you would need to do is make it rectangular patchwork, and I would use the birthing method to hide all of the raw edges and then hand slip stitch the end by your elbow. :wink: Then it is just the matter of attatching the webbing, D rings and the velcro to make it adjustable.
