Wow--sounds like a bad situation. Couple thoughts--definitely ask for a referral to an occupational therapist--they figure out how to help you continue to do the things you want/need to do and have an amazing amount of resources and tools that can help you. Your PT is there to help you strengthen your arm and get it working again, the OT is there to help you get back to normal activities.
Second thought is to get an Accuquilt Go Big--the electric one. You can cut an amazing amount of things with the correct dies. Another thought is that many shops offer BOM and for an extra charge, may be willing to do the next step of cutting the shapes for you. Lastly, while you are progressing toward total healing, you can get some kits that use prefused applique shapes--most catalogs have them, and work on those.
