I thought I’d post an idea for anyone who wants to try dyeing yarn at home using ingredients readily found in your kitchen.
It’s more of a staining method rather than an actual dye but it works all the same
Check it out!

You only need some simple ingredients and 1 hour of your time:

Ingredients:
Yarn in hanks (preferrably animal-based. Mine were 100% superwash merino)
Distilled vinegar or alum (it’s a pickling powder found in your grocery spice aisle)
Main ingredient listed on each ball (see below)
Coffee Filter
Shampoo or dishwashing liquid

How-to:
1) Prep yarn by soaking it in a water-vinegar solution for 30 minutes to an hour
2) While the yarn is soaking, put main ingredient in a blender or food processor and liquify
3) Pour blended liquid into a small pot and add water (just enough to cover the yarn)
4) Boil for 30-40 minutes until the color of the water becomes dark and the solids sink to the bottom. Let it cool
5) Drain the whole thing through a coffee filter.
6) Place yarn in the colored water and heat the pot at the lowest setting possible. Stir occasionally but very gently (so it won’t felt)
7) After a good 30-40 minutes, turn off heat and let it cool
8)Drain, rinse and wash it in a gentle shampoo/dish detergent solution
9) Rinse again until water is completely clear
10) Roll it in a towel as to remove all traces of moisture and hang to dry.

Ta-dah!

EDIT ok, the tomato leaves are from my backyard and the cactus pears & kimchi are a little out there but still totally non-toxic!
