Tell us about yourself!
Is your be-able group in the USA as well? If not, I would be interested in starting a branch here in my home area. With your permission I would like to make these and give them for free to wheelchair users who need them.
As a leather worker I would like to give a suggestion. When making your stitching grove it should be placed a distance roughly equal to the thickness of the layers you are stitching. This allows for the strongest join as possible, and you won't have to trim your seam to get a good look.
