well over the last few weeks i came to the result that a cheap product called vellum (found at staples) works the best for burning your screens. also ...
I'll show all you cheap people how to screen print. I build or make %99 of my stuff. This is probably the cheapest way of doing screen printing. Only thing is, is that you will have to want to make many screens for it to pay off. But I've made many screens and truly love making people shirts, and even more.... saving money.
Step 1: The screens
the screen frames are pretty easy from scratch, I use 3/4 inch wood (lying around, so it doesn't truely cost me anything) and cut 1- 1 1/2" strips. I then make 45 degree cuts on the corners. My screen's dimensions are usually 18" X 17" for a regular design but for full shirt designs I use 21" X 18". but after the 45degree cuts have been done they should all set flesh with each other. now take out your pressurized staple gun and shoot each corner this should hold the frame together. Now its time to stretch your fabric.
Step 2: Stretching the fabric
now its time to do the most annoying part of screen printing... stretching the fabric. if anyone has performed either stretching a canvas or made a projector screen will be familiar with this process. To start out you will need the fabric to stretch. I buy mine at my local wal-mart the fabric needed to do this is called a "mesh" fabric, if your not %100 on fabrics ask a employee they are sure to help you out. most of the time I buy my fabric for $2 a yard so it ends out being pretty cheap. Now its time for the sketching of your newly purchased fabric, I start out with 1 staple on each side and progressively add 2 to each side making sure that I tug on the fabric as I go to each opposing side. after a while and a few hundred staples I finally finish my screen.
