This month we are using a product that can make wet-felting much easier and less "work". Artfelt Paper is used as the base of the process and will be washed out when the wool fibers have been shrunk and felted.
You are using the foam and felting needle to baste your fibers to the Artfelt Paper. The actual felting will be done with water and your dryer. Determine the size of your project and cut the Artfelt Paper accordingly. You may have to move it around your foam in order to do the basting.
You will needlefelt baste the wool fibers in layers onto the Artfelt Paper, first horizontally and then vertically, gradually building up to the desired density. You may want to draw a design on the paper and "paint" the areas in with specific fibers. While these photos don't show it, be sure to leave a margin of paper around the fibers.
Let the felted wool dry flat. The piece can then be used as the background or applique. You may want to needlefelt other yarns or fibers onto the felted piece.
If you are interested in making a weaving similar to the sample above, simply lay your fibers in a grid keeping areas open. Wet, roll and dry as instructed above.
