I've been really working on my process for table rugs - any rugs for that matter. When I first began felting wool I discovered that layering shapes onto dry wool and then trying to wet everything down often just created a mess. The shapes didn't stay where they were supposed to stay was the first big problem. The second really big problem was that I would end up with holes in the wool because I couldn't tell where I needed additional wool.
So, then I began needle felting my shapes so that they stayed together during the wet felting process. I still couldn't tell where my wool was too thin and ended up with thick and thin spots in my rug. Now I needle the whole thing. I can pick it up and hold it toward the light and tell immediately where I need to add wool. I can also "paint" the canvas that is created when one needles the base wool. That is what I discovered when creating this particular table rug. I was having so much fun "painting" with my needle that I got carried away into another world.
The wet felting process goes so much smoother when the whole rug is needled. All the shapes remained clear. The colors of wet felted wool tend to soften as the base wool is worked through. Its really a beautiful thing.
