This is from Picperfic who is also found on etsy and a UK based seller. It is 75/25 organically farmed merino/mulberry silk in the colourway Merisil.
It was in the description of the fibre that it was well blended which is what particalarly drew me to this fibre. I have worked with silk blends before but there is always a thick line of silk running through which I find can make it harder to spin. This is very evenly blended and I will definitely be ordering from her again.
