Currently I just use small sticks (popsicle or tongue depressors), lay them side by side and slap on some PSA grit to the lot. I then separate them with exacto knife cuts between the sticks. Shop floor and benches are littered with them but one is always lurking near by. Handy items those mini sanding sticks (either metric or imperial!)
In my household tongue depressors are big planks... will not fess up whether that's for SWMBO or me, for fear of death.
I used to eat popsicles by the dozens just for the sticks and also used them with thin strips of sand paper glued to it... However, I often found that I mainly use the tip, or the first 20.32mm end length of both ends and the middle was wasted. Cutting the tip off left a ragged edge that I sanded down with the tip of another popsicle, also wearing it down... and the loop goes on.
With these, I just roll the belt and get a new "tip" surface.
At my age, my second favourite word, after "vino" is "convenience"... just before my next favourite word which is prefixed by "Inconti", that being "nence"!
If your first cut is too short... Take the second cut from the longer end... LBD
