Easy screen printing tips?

[motherbirth]

I want to make a silk screen type thing so I can print some onesies. I thought about doing linoleum block prints, but with a 9 month old I am not sure I have time to be carving linoleum. I'd like something that's reusable (so doing the freezer paper stencil is out). I haven't done silk screening in years and the method I used involved some kind of gelatine that you could cut with an Xacto knife and I never see that for sale anymore. So.... what is the easiest way to make a reusable print given that I have a LO around?

I can't wait to try this stuff.

I use acetate film aka transparency film. I create my images in illustrator, print it out then cut with an xacto knife. I did a tutorial for it on my blog. The tute is actually done with a regular paper print under the film b/c the image was larger than what I could print onto the film but the concept is the same.

Repositionable spray adhesive (try typing that fast when NAK) is your friend when playing with stencils, IMO.
