Several years ago I purchased some huck towels from the Rag Lady (on Amazon). Over the years they got a bit dingy and I couldn't find any replacements I liked. I've been working on learning to dye fabric and so I have leftover dye. I use it to over dye those dingy faded towels.
Here are some of them (some are in the laundry)
This is how they look before dyeing
I soak them in soda ash solution before applying the dye. That is my dye solution in 2 oz bottles.
