I have 1 of those rubber blocks with the embedded tacks. They work good but but the rubber can mar mating surfaces, the sandpaper needs trimed and you need a screwdriver to get the paper off for a change.
This design was in an e-tip a few years back. I sized it up so it's 1/4 of a sheet long wise and full sheet width wise (no trimming). The paper is held in very tight and doesn't wiggle (like the store bought one). 1 end is rounded and the other square for getting into corners. The paper is held in with 1/2" tubing. I made a bunch for the kid's workshop to give to them but made about 5-6 for myself. Then I have at least 1 per grit to eliminate changing paper to use a different grit. The less hassel (and less time) during sanding makes me a happier sander.
