So while things are drying and firing I'm gonna show you guys how to make this...
First grab your tools.
I use a pneumatic staple gun but you could use nails.
You'll need at least four Miter clamps and as many spring clamps you can get
Also you'll need wood glue.
So first, cut out your wood board, whatever size you may need.
Then cut what will be the framing.
And for that we will use the Miter saw which can conveniently cut at 45 degree angles so we can achieve our 90 degree corners on our frame.
Make sure both sides are in opposite angles or it will not work out so well
And thats basically it. Do make sure you sand the edges so no one handling your work gets splinters because they will hate you.
And as far as preparation before you paint you have choices:
you can use gesso, matte medium or oil primer to name a few.
I usually us matte medium because it lets me start from a toned surface.
Well I hope that's been helpful and let me know if there are questions or comments.
