Felting Wool Colors. You only need a little bit of each color. When I began felting I became frustrated at having to purchase large amounts of each color I needed when I only needed just a teeny bit of that color.  When I began to teach needle felting I started to offer my stash to my students in quarter ounce balls. Now that I have my own shop I carry over 100 colors of quarter ounce balls!! Mostly Corriedale and reorderable. A lot of my own hand dyed colors as well.  Only a tiny bit of merino in black and white and some unusual blends.   A lot of you want to purchase on line. It is not cost effective for you to buy one ball and pay shipping so what I have done is made packages "by the rack" as it is displayed in my shop.  
I charge 1.00 a ball in my shop. The cost to you is the same as my wool shop, with shipping added deepending on the number of balls in the pack
Each ball is approximately 1/4th an ounce.
The hand dyed is dyed with acid dyes and the fiber could be anything I was dying at the time!
The outside of the bag is labeled with the type of fiber
