Starting to fix the design, I rather like how the bubbles and plastic overlay the design underneath, the stark lines are created by the silk cocoon bumps.
Removing the plastic to rearrange some of the prefelts that have moved while rubbing
After lots more rubbing and a bit of throwing I gingerly opened up the cocoons, some of them had rotated so that the holes I had so neatly cut to let the dye in were no longer at the top.
I'm a little bit disappointed the edges to the orange prefelts have gone rather fuzzy (I should have made the prefelt firmer before cutting it up) but I think I can visually sharpen them back up with a bit of machine embroidery.
Some close ups of the felt while it is still drying:
I love how this cocoon produced a tail of loose silk as I opened it up:
Next time, adding some embroidery and thinking about how to hang / frame it.
