In the past, I have bought many cheap sanding blocks on the market. For the most part they work just fine but I have often found that they are either not ergonomically designed and are uncomfortable to hold or replacing the sanding paper is a royal pain in the ass. So after cursing many sanding blocks I decided to it was time to take the DIY route.
Step 1: Choosing a sanding block
After some research on the internet I decided to buy an Anderson Smooth Touch Sander. It is not at all necessary for you to make the same choice. You can easily replicate the process with any other materials like wood block, blackboard duster etc. Choose a sanding block which you are comfortable holding.
Take the sanding block of your choice. I chose an Anderson smooth touch sander 250 mm.
