Don't have the space for it? Bullshit. All you need is space enough to lay your target fabric flat, which you obviously already have. All it takes to do your own is a piece of framed silkscreen, your stencils, ink, and a few tools - it can be as large or as small as you want. When I did it, the one that I used was about 18 inches square, but the teacher had a bunch of other examples that varied in size and complexity.
