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 the shop. The cost to you is the same as my wool shop, with shipping added 8.50 priority mail.
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
If you need more of the corriedale colors I can create a custom listing for you.
