Any color (or white) that you see is added on top of the core wool. Here's a peek at the selection of wool that I use. (And check out the vintage shoe rack where I store it all--I snagged that from a local store that closed.)
I use barbed felting needles to shape the wool. There are different sizes and shapes available. I typically use a star needle, which has four edges and a couple barbs per edge. There are triangle needles as well which only have three edges, so less barbs. The more barbs, the faster the felting. I can use a single needle, or sometimes I hold a couple needles at once.
I also have another tool that holds up to six needles to help me make basic core shapes and to cover larger areas quickly with colored wool. Looks menacing, right?
I know you're wondering...so I'll tell you. Yes, I do poke myself. Not too often (anymore), but it still happens. And yes, it hurts.
Next up, a little demo!
