well i just started to do a bit more sliding and i found that my homemade glovers from bunnings were really loose around the wrist... so i decided totry and build a strap into the wrist part.
materials:Velcro, Araldite, homemade slide gloves and scissors
so i started by cutting the little stitched part of the cuff like this:

then i cut along the cuff a little bit:

then i cut a little diagonal thing so it pulled under the other part instead of folding:

checked the tightness and fit:

cut the velcro strips:

and then glued on the velcro:

ill post up a pic of them on my wrist when the glue dries better probably in the morning
feel free to add suggestions criticism and better ideas or different materials that would work
