Again this is a great article!
I had a similar experience recently with a beautiful hand dyed top I picked up from a local dyer. I wanted to create a striped batt by separating out the yellow from orange from red. The colors blended a bit more than I thought I wanted, but the end result is two fantastic batts, with sparkle (I like sparkle so I added sparkle), that I plan on spinning separately and then plying together. As soon as I am done enjoying the fluffiness that is their batt form.
Happy Crafting, and read this article. Short but sweet!
