you can make screens using chiffon (I think is what its called, its less expensive compared to buying silk.) then get one of those hoops for cross-stitching or some shit and combine the chiffon fabric and the hoops, and you'll have your very own diy printing screen. thats how I always did it and it works fine for me.
i got a 3 pack of these cheap 4x6 wood frames from a thrift store (also available at michaels arts and craps) and my girl managed to score a few yards of some screen, so i made some sticker screens (and one for our christmas cards) and it was quick and painless. all you do is pull out the little metal tabs, lose the glass, and staple the screen on. the small size also makes stretching it a little easier for a one person project, and you also don't have to worry about filling a lot of extra space as you would on a larger screen (unless your a smooth operator and do 4 or 6 stickers on one screen). anyway, the easiest way is to pop one in the center top of the frame, then do the same to the bottom, then the sides, and then do the corners, switching to the opposite one (top right, then bottom left, so on so forth). don't be afraid to use alot of staples, and get that sucker tight. most people will tell you to watch the weave and keep it from getting wavy, but i did it while drinking so i said fuggit. but you should keep the weave parallel with the frame. you might want to use some rubber cement or something similar along the bottom of the frame to keep paint from pooling in between the screen and frame, it can get messy without it. then you slap on the screen filler or emulsion, how ever you prefer to work, and biggity blap you have a screen. they sell squeegees that small but i found that a card like you get for savings at the grocery store worked fine. drying space can be an issue, but we are all creative people here.
it wasn't emulsion, it's screen filler. you just paint it on with a brush all the spots you want blocked out. isn't always as clean as emulsion can get, but it's a lot simpler to use if you know how to work a paintbrush (sometimes still a challenge for me)
With painting with the drawing fluid, if a bit splatters youre fucked cause thats gonna show up on the screen filler and make your slap look shitty.
you can always go over spots you didn't mean to leave open after you get the drawing fluid out. and if you skip the drawing fluid and just paint the image in filler if you mess up and are quick on it you can use a small stiff paintbrush, some water, and a paper towel to clean out the filler before it dries.
haha. lead based stuff is awesome. i've always just used acrylic paint, and it stands up to the elements pretty well, i watched a sticker by my work for like 2 years and the sticker adhesive died before the paint.i use it because it's cheap (or easy to lift) and it is easy to clean. and it doesn't give me cancer when i do long print sessions in small closed rooms.
