Hi Kent, yes, please send any advice! We want to get these right the first time. We have a template we are hoping will fit all sizes. Go to foosball.com, left column,Interact, click on Staceys workshop and wrist braces. We are trying to make one with different cut-off points. Kindof a one size fits all. Let me know if you think that would be better than what you tried.
Looking forward to hearing from you!
Debbie
