I recently learned about “compost dyeing” through buying an e-book from Kimberly Baxter Packwood, so though I would give it a go. I used a piece of old sheeting, quite lightweight and rather worn after constant use. I made a bundle using a few previously used pieces of pomegranate skin and a few fresh radish slices, a small piece of copper pipe and a bit of fine rusted wire, with elastic bands to hold it together. I soaked it in vinegar solution and then buried it in the compost heap for a week.
