I have been trying needle felting with some previously dyed pieces.
The fabric pieces on top seem to float and yet also they are part of the fabric and embedded. I tried pieces of blanket, silk voile, patchwork cotton, cotton gauze and rust dyed cotton.
And then I made a less random sample with pieces of blanket and rust dyed cotton.
These are my carrot top samples. There wasn't a great variety, however some of the differences are very subtle, and so I think generally carrot tops could be used without any pre-mordant, except for th cotton fabric which I soak in diluted soy milk. I soak it, dry it and then keep for as long as possible on the shelf before I use it. India Flints book "Eco Colour - botanical dyes for beautiful textiles" is a wonderful source of all sorts of information
And out the window - a beautiful rhododendron which is just flowering. And if you could just see over the neighbours fence you would see that the sun is shining again.
Today my plan is to dye a piece of blanket in onion skins, straighten some old foraged autumn leaves and then put together some pieces of fabric and dye them in the piece not in pieces as I normally do.
