What you’ll need
Stick On Coarse Sandpaper
Stick On Fine Sandpaper
You need more than one type of paper. One coarse to get out all the bumps&one fine to smooth it out
It’s easiest to sand if you have something more physical than paper to hold onto. Try wood, or foam
Begin sanding with the more coarse sandpaper first. Get all the bumpy and hard areas off.
You can also use sandpaper to correct imperfections. Like wood that has been cut wrong, or dents.
Change your sandpaper to a more fine sheet!
Sand the wood until you can go over it with your bare hand and it feels soft and smooth. And viola!
