I boiled water, placed a tea bag into a stainless steel bowl and submerged the sock. It doesn't seem to be taking the tea stain. I also placed about a tablespoon of white vinegar into the bowl as a mordant as done with easter egg dyes. I will leave the sock submerged overnight. If the sock has not accepted the stain by then I will add my coffee grounds to the bowl. If neither of those work, I will spray paint the sock.
I have seen gold finches on the sock but have not had the opportunity to photography any there. I did capture house finches at the bird bath. The house finches do not feed from the sock nor do chickadees, nut hatches or titmice.
