Awhile ago, I started making picture frames for our art prints.
This arose out of several needs: 1) the big wood frames cost way too much money in the store, 2) these frames of preset size often do not fit the print size, and 3) they are usually only available in one or two colors.
So I started making them my own, inspired by an old friend of ours who was an artist and made frames for his canvases all the time.
I have experimented with several different strategies for joining the pieces and my latest version seems the simplest.
Materials:
Buy several 1"x2"x 8 feet wood strips from your local hardware store. Cost is usually around $1.50 per strip. (Note: this means that the board is actually 0.75"x1.5"x ~8 feet long).
3/8" dole pole for around $0.70. Should last at least 3-4 frames.
Buy a box of wood screws. Cost is around $5 and will last you for many frames.
Buy some craft paint in appropriate colors. Cost is around $2 and will last many frames.
So total cost per frame is probably around $3.
Method:
Cut the wood strips to the appropriate size. Want the strip to cover about 0.75 inch of the print usually, as the white border tends to be from 1-2 inches.



Lightly sand cut edges so flush.

Using a 3/8" drill bit, drill holes for the screws to connect the length-wise ends to the height- wise ends by marking in 0.75 inches from the ends of the length wise sides. Only drill about half way thru the board.
Using a square to assure right angles, drill pilot holes for the screws from this point all the way thru to the other board.
Then insert screw and tightened well. (I found that a power drill was useful to do the main work, but needed to hand-tighten to get totally tight without cracking frame.)

Then place a little bit of wood glue in each hole and insert dole. Cut dole off flush with board using a hand saw.
Sand the entire product smooth and paint with three to four coats of appropriate color.

Then staple the print directly to the frame using a staple gun.
Add a hanger and the framed print is ready to go.
Here are some finished products:
