DIY Hobby Sanding Boards | 3M Super 77 XPS Foam

We started out with a simple DIY sanding board video and once we got to the 3M Super 77 adhesive, we had to keep going and make a little diorama out of XPS foam! I've been using this simple idea for a perfectly flat sanding board for years and thought I'd make a few new ones as the original had become a bit rough around the edges.
Lots of times I'll find I just need a handful of swipes on sandpaper to perfectly square up a model kit's walls, a plaster cast base or even bits of styrene during a build. I much prefer holding the piece I'm sanding against a solid base, rather than holding the model and also holding the sandpaper as inevitably one or both hands go off on a slight angle, and there goes my straight line.
This is an easy and inexpensive way to get a solid, reliable and flat sanding surface that doesn't move or flex so you just have to focus on the piece you're actually sanding.

I really like the technique with the single edge razor blade looks terrific

Thank you! As I mention in the video, the no-cut gloves are a cheap bit of insurance :) Prior to using them, I'd get a little too comfortable abound single edge blades, never a good thing. I find the gloves a good reminder to myself while working with these blades!

Why not 2, 3, 4 grits on same board? That’s a lot of surface for reasonably small parts sanding.

You certainly could! I tend to use a long, light stroke... like I do for spray paint or airbrushing, so for me the long surface works great.
