I want to try making a pair felted slippers. locking fibers=increased durability, right?So I made some test swatches yesterday and tried felting them to see how well the wool felts and amount of shrinkage. It looks like the pieces shrink up more vertically than horizontally. I lost about an inch vertically and maybe 1/2 an inch horizontally. The wool is mystery wool, I got it from a kit a while back. Its not the most premo stuff, but I do like the colorway. So I've started making the first slipper.
