The piece above has finished oxidising and has been ironed.
I clamped 2 pieces of wood on the fabric above after folding it into a tight rectangle. I was disappointed when I opened it up to find there were some little spots on the white area. When I looked back at my wooden blocks I realised one of them had a little hole on it so some dye creeped in.
