Step 2: Build Your Screen
1. Take apart the picture frames. Remove all the little metal bits and put the glass aside. You will need a piece of glass from a frame smaller than the one you are using for your screen. Watch out for the edges of the glass. Don't cut yourself.
2. Cut a piece of the curtain rather larger than you need to cover the front of the picture frame and wrap around the edges. You are going to stretch the curtain over the frame just like stretching a canvas for painting. It helps to keep an edge, so that you have a straight line to go by.
3. Stretch the fabric over the front of the frame and staple it into Place. Try to keep the fabric as straight as possible. If you staple it on diagonally, with the grain of the fabric too far off from the square of the frame, you will run into trouble later. You don't have to be too anal about it, just try to put it on straight.
Staple the fabric onto the sides of the picture frame fairly close to the front edge. Pull it hard to make it as taut as possible.
I recommend putting a couple staples on one end, then a couple on another end, then on one side, and then another, and keep going round and round, pulling all the time.
4. Cut the excess fabric off around the sides of the frame. Don't cut too close to the staples or the fabric will fray and come loose.
That's it. Now you have a screen for printing
