Ok, so now add the glue to one side of the pad and apply one sheet of sandpaper, repeat with the other sheet of sandpaper on the other side. Be careful to remember which grit goes on which side of the pad. You can use a permanent marker to indicate on the top of the pad, the grit number so you know which one is which when you use it.
This little trick has saved my arms and shoulders and my sanity from alot of trouble. I hope you like it. Try it in the new year and let me know if it works for you. Now, this is not very handy for the sanding of intricate pieces but works great on flat surfaces. When sanding crochet hooks, it use to take me 15-20 minute for each grit and my fingers and hands were all cramped up. Now, 3-4 minutes and I'm done and my hands are not screaming. I love it!
Merry Christmas everyone and a wonderful new year!
