One color yarns to bulk up yardage for a project. Yarn ordered with an Evolution will be dyed at the same time for the best match. Coordinates for the two end colors of a colorway you already have are available with the understanding that I'm doing my best to match something I don't have in front of me, based on old formulas, mixed with dyes that change from the supplier without my blessing. That said, I am happy to dye the yarn you need to finish a project old or new. If I don't get it right the first time, I will work with you for a solution. Contrasting Colors are available too. Include the color you want in the comments at checkout If you only need a small amount to bind off etc, please contact me for assistance
