Colonial Needle Fiber Blender Tools for Felting, Spinning & Crafting - Perfect for DIY Wool Projects & Textile Art

As other reviewers have stated, they are a little small, with the plates approximately 1.5inx2in, and the surface area where the needle teeth are- are smaller than that.I bought these to use with blending two wool roving colors from Michaels. They work very well, and it's best to blend colors in small batches, to really be able to 'brush' through the fibers, otherwise it's just a big blob. I also bought some felt sheets from Michaels (since those have more color range choices), and used these tools to separate those fibers, and it worked pretty well! This was really helpful because then I didn't need to buy so much wool roving (which can get expensive!) and the sheets are cheaper and came in a color I needed.Overall, a very useful tool to have for small projects!
