I bought my gaywool from my lys Vulcan's Rest (http://www.vulcan.mbweb.com/) They had bigger jars and smaller ones. Perhaps you could get some of the smaller jars.
I also recently purchased Jaquard Dye from Dharma Trading Co. http://www.dharmatrading.com/ I bought the 1/2 oz jars of 4 colors - about 4 - 6 dollars each. I also was able to buy nice plastic containers, gloves and other accessories. Very reasonably priced.
