I did get around to trying out the silk paper sheets that I made not so long ago. I first tried using the tufty bits from around the edges of the sheets to see how the paper felted. The piece I made looked a bit pale, so when I layed the wool out for the new piece, I used darker blues and purples for the background.
I was really pleased with the way it felted, though for some reason it shrank unevenly. The first piece I'd made had also shrunk unevenly, but I just assumed it was the way I lay the paper, so there were more fibres running in one direction. But both pieces had two equal layers of merino and I didn't pay particular attention to the silk paper fibres and which way they ran, and since most were two layers it shouldn't have mattered.
You can see from this angle that the silk paper felted in really nicely
