i used the same dyebath - old dupion silk this time from an op shop wedding dress.
i scrunched up the biggest piece of fabric (about 1 metre square) and for the black rimmed circle effect used metal beer bottle caps (crown seals) loosely held in the bunched up fabric with rubber bands
i love dyeing wool and silk with eucalyptus leaves because it's so easy - no mordants, no poisons, no hovering. i use a bunch of eucalyptus leaves from the florist and just boil if up in a big cheap stockpot - i tie the fabric and bung it in and just leave it. the first lot i boiled up on friday, left it to steep over the four days we were in apollo bay and then removed the pieces and let them dry.
