I used loquat leaves to dye a thrifted solid white cardigan. I had a very interesting thing happen on the arm pit region. I don't use commercial deodorants, but the leftover chemical residue from the previous owner's deodorant caused a reaction that actually dyed the armpits of the cardigan much darker than the rest. This is such a hard color to correctly capture on camera. The cover image is the closet to it. It's a soft, true baby pink similar to Pantone's 196C.
Here's the dye problem with the armpit.
I can't wait for my next dye project. I've always wanted to dye with natural products, and now I have some skills to keep going.
