Welcome to the forum! I have seen your work on Facebook and really like how you work your leather.
I am past president of the local leather guild in Austin, Texas. As a member of the guild and veteran (Army), I am part of a group that our guild sends to the VA hospital near Fort Hood and put on a leather demonstration. Since our guild has been doing these demos, we have found that the most common asked for demos are any hand stitching techniques, anything lacing, geometric and basket stamping and basic tool manipulation. Every time we go, we are amazed at the artistic abilities of the service veterans that use the craft shop within the hospital.
Side note: if you can the coordinator of the local VA hospital craft shop, they are more than willing and welcoming to our craft. You will be surprised. My suggestion is that you keep it small and simple. Key fobs, coasters, credit card sleeves, etc.
Good luck and let me know if our guild can help you down the road.
Thank you for your service!!
