safe dyes for woolen baby clothes

[CalmCenter]

I have some beautiful natural colored woolens for my baby... but we live outdoors a lot and they get dirty so fast! I would like to dye them a deep color. Any suggestions for safe, non-toxic dyes I can use on wool? Thanks.

I like Wilton food coloring pastes for dyeing wool. The are readily available at big box craft stores, fairly cheap, can get you nice bright/dark colors, and are intended to be eaten, so definitely non-toxic. I don't know if you were looking for something "natural", but some natural dyes are poisonous, and the chemicals (called mordants) that you generally need to make a natural dye colorfast can be fairly toxic. Since I don't have an extra set of pots and utensils and  since I make my daughter's food in the only place I have to dye yarn (our kitchen) I would rather stick to food coloring and white vinegar, which won't hurt her (or me or DH) if some residue gets left behind. 

There's a great article in Knitty from a while back about dyeing with food coloring:

The article assumes you are dyeing not-yet-knit yarn, but I'm sure you can extrapolate how to dye the clothing.

Also, If anyone knows of a way to get dark colors with natural dyes and no toxic chemicals, please correct me--I would love to know what process you use, as I have never found a way to do it.

Many dyes take well on silk and wool with just vinegar to acid dye it. Practically any pigment in the hot acid dye bath will stick to one degree or another. Remember not to move or stir hot wool or it felts. http://www.dharmatrading.com/html/eng/9323186-AA.shtml?lnav=dyes.html there is a natural dyestuff source.

ETA alum or cream of tarter also help many natural dyes to fix well, they're sold in the spice section at the grocery.
