Here’s an easy project that even the least crafty can do, using onion skins. Consider this your base recipe. As you continue on your dyeing adventure, you’ll have to adjust the amount of water and mordant to suit the material used, but the basic steps are the same.
Metallic agents called mordants are needed by some fibers to help the dye adhere. Alum and iron are the two mordants considered safest by many natural dyers. They can both be sourced from natural dye suppliers, such as Earthues.
Keep equipment used in dyeing separate from that used in cooking.
You will need:
4 ounces wool yarn
1 teaspoon alum
1 teaspoon cream of tartar
4 ounces red or yellow onion skins
