Elderberry Results

Here are the pieces I dyed with elderberries and elderberry leaves now they are dry.  I am really pleased with the results. The black spots on the bottom left cotton piece below are the result of a mould growing in my dye bath. Oops. I think they look interesting but can anyone tell me if the mould could be nasty, even though the fabric has been washed?

This last one is my favourite, the fabric is very fine recycled kimono lining silk.
