Thanks for the replies. I ended up getting the Fotospeed Bromoil Kit which has 10 sheets of 8x10 bromoil paper. I guess I'll cut it down to 20 8x5's to practice on.
You might want to start with a few 4x5s. The larger image sizes are definitley harder to create. I usually work with 5x7 sizes. The larger the image, the more difficult it is to keep the layer of ink even (Especially if you have any large areas with very even tone). The print will start drying out before you can get a complete coat on it.
I would also suggest that you start with images that have a lot of varying tonal areas. Tree foliage, for instance will probably be easier to ink than a blank grey sky.
Also, start with the stiffest ink you can get. The more the ink is let down, the more precise control is needed.(brushwork/temp control). The best stiff ink I have found is the product made by David Lewis. I've tried a lot of fine inks, but David's inks are much stiffer than anything else I've seen, and are the easiest to control for people starting out.
Just some suggestions.
Have fun. its a really beautiful process.
