1) Miter the edges of your Frame Pieces:
Using an 8 foot length of the1x4 fir, come in about an inch from the end (so you aren't using any roughed up edges) and make a mark near the top of the board. This is your starting point. From that point, measure along the top edge and make another mark.
Make a 45 degee Miter cut at your starting point mark. The mark represents the top of the angle. The cut should be inwards. If using a Miter Box as shown here, ensure the wood is snug against all the edges of the Box. Hold securely in place while cutting. You may want to get someone to help (my wife was very obliging).
Now make a 45 degree Miter cut . The angle should, again, be inwards. Remember, the mark is the top of the Miter angle.
Do the same with the other 8 foot length of fir.
_________Mark the top of the board
This is the top of the angle cut

2) Square up and Secure into Place:
Lay out your 4 pieces to make a large rectangle.
Using the square, even up on of the corners, making sure there are no spaces along the edges where your straight edge meets the wood.
Lay one of the corner braces in the centre of the corner. You want exposed wood on either side for stapling your screen to later. Mark the holes.
Pre-drill the marks (as dead centre as you can) with a 1/8 inch drill bit. Make the hole just deep enough to start the #10 screw that is to follow. This hole will prevent the wood from unnecessarily splitting on you when you put the screw in.
Ensure your corner is square once again and screw the brace into place.
Repeat for all four corners.
3) Attaching the Material - if you do not wist to staple we do sell frame clips
Roll out your material on a clean flat area. We use carpet so we do not damage or dirty the material. Lay your frame, braces facing up, onto the material.
Measure the centre point of one of the shorter frame boards. Put a mark on the inside edge of the board (the side with the metal frame braces showing).
Wrap the material around the top of the frame (No need to be tight just yet, that's coming up). Staple the material at this centre mark.
Now move to the shorter frame board directly across from the one you just stapled.
Measure the centre of one this frame board as you did the previous one.
Wrap the material around the frame and, this time, stretch the material so it becomes tight. Staple into place.
Do the same with one of the longer frame boards and finally the longer frame board directly across from the this one. When you're done this, the material will have a "diamond" shaped stretch pattern to it.
Choose one of the longer frame boards for this next step.
From the centre mark where you stapled, move about 3-4 inches to the right. Stretch the material by pulling it over the frame and to the right as you do so. Staple into place.
Now move 3-4 inches to the left of that same centre mark on that same frame board. Pull the material over and, this time, to the left as you stretch it. Staple into place.
Repeat this back and forth method until you've stapled the material to the length of this frame board.
Leave about 2 inches unstapled at the edges for last (do the edges last).
Now do the same on the longer frame board directly across from this one. Then do the same to one of the shorter frame boards, then do the shorter frame board directly across from it. With those, you may have to work sideways. The frame will be too tall to work with standing on these ends.
