Help!!

I am hoping someone out there can help or tell me where to look for instruction on dyeing my wool roving. I purchased this kit which includes various cushing dyes, citric acid crystals, pre-wetting solution and a measure cup. It also came with a book but it deals only with dyeing wool fabric. I'm sure parts of the process are the same but I'm just unsure and don't want to destroy any of my roving. Any dye experts out there?
