My husband and son gave me a Fancy Kitty fiber blending board for my birthday, and today was the first time I tried it out. I took every little greenish scrap of wool I could find in my stash and blended them. It's mostly merino and corriedale but also a bit of mohair. I like how it turned out! I will have to finish up the yarn I'm currently spinning so I can see how this spins up! A drum carder was really out of my budget range, and I think this board will be great for my blending purposes, and it's so portable too!
*Update* I finished the yarn -- here it is! 101 yards. I named it Green Giant because it's a big, bulky corespun. It's a bit overspun, but very soft. I know I should run the core yarn through in the opposite direction before corespinning in order to get a really balanced yarn, but I was WAY too impatient to see how the colors would turn out to do that!
