I finally got to play with mine when my Spinning Guild had a "Blending Board Party". A bunch of us got together and just played for an afternoon.
I focused on making vertical stripes and used colours that would usually not blend well together. Because you can be so precise with how you lay your material down, you can do interesting things like that and maintain the colour separation as you spin. You can really pack a lot of fibre on it and I ended up pulling three rolags off for each palette I filled.
I spun them up and really enjoyed the results. It was a little challenging to spin because I really used a lot of different types of fibres, some of which are much easier to spin. All in all, I really love the results and can't wait to play with it more! Now, I just have to decide what to do with the finished yarn… hmmm….
