To start this project, you'll need to cut the timber and backing for your frame. You can have the MDF board for the backing cut at your local Bunnings. We had our backing board cut to 300mm x 400mm, and we made our frame 435mm x 335mm.
To cut the timber for your frame, make a 45-degree mitre cut at the end of your timber and measure out 435mm for where your next mitre cut will be. For this cut, make the cut in the opposite direction. Check that your measurement of 435mm is from long point to long point to get the right length.
With your first 435mm length, use it to mark out the second length for your frame. Again, you'll need to make a 45-degree mitre cut in the opposite direction.
Repeat these steps to make two shorter frame sides at 335mm, with opposite 45-degree mitre cuts at each end. Remember, the 335mm length is from the long point to the long point of each cut.
Put the four sides of the frame together to make sure they fit. Then use some PVA wood glue to join the mitred ends together to make the frame. Wipe off any excess glue. Then use four mitre corner clamps to keep the frame in place while the glue dries. Once you have the clamps in place, re-tighten them to make sure the frame is square.
Once the glue has dried, remove the clamps. Give the front of the frame a light sand with 240 grit sandpaper for a nice smooth finish.
Turn the frame over and insert the picture or artwork facedown. Place the MDF backing board on top of the picture or artwork.
Now all that's left to do is fix the sides with the frame stays. They need to be in the centre of each side of the frame. If you're using a hardwood and it's difficult to get the stays into the timber, pre-drill the holes using a drill and 2.5mm drill bit. Secure the frame stays with a screwdriver.
We've left our frame natural, but you can varnish or paint yours any colour to suit your home. Then you're ready to hang the frame wherever you like with either a hook or velcro hanging strips.
