|215g of onion skins collected in my Grubby, a counter top compost collector given out by the city. I have vermicomposting in my kitchen so this bin sat unused until now, it's perfect for onion skin collection.
For the actual extraction, I put the skins in a paint strainer and then large pot of hot water and slowly raised the temperature to the 180-190F, a bit below boiling. Everything I read said to boil the skins, but I am not sure that is good for the color. I have nothing to base this on, but I feel like extracting at the higher temperatures will result in more browning so for this go I decided to keep the temps on the lower side. This might mean that I didn't get as much color and it might result in a different color, that's something I will have to address later in the summer. One last note on the extraction- onion skins smell like onions when you add water (surprise, right?) so they might be best used outside.
|I really love these 5 gallon paint strainers, they keep all the little pieces together so that you can pull it all out at once and get straight to the dyeing.
|Final dry skeins. On the left is the regular wool and on the right is the superwash,.
|The difference in the two colors is pretty dramatic, hard to believe they came from the same dyepot.
