Step 19 Sand the edges to avoid splinters and make it pretty

I'm using a palm sander, with 80 grit sandpaper on it and going around the get rid of splinters and round off the corners. If you don't have a palm sander you can do this by hand with a piece of sandpaper. You might get bored before your corners are rounded off, but you could certainly sand any pokey wood splinters off by hand.
