RE: marbling bandannas. I've made most of my own tanks out of wood -
think they are called 1 x 2;'s or 1 x 4's for the sides and scrap paneling
that I found for the back, then lined them with visqueen which I duct taped
down on the outside. You can also make a pvc "frame" and line it with
visqueen (clear plastic sheeting). I used a double layer of the heaviest
visqueen, I think it was 6 ml if I remember correctly and I marble bandannas
from dharma and silk scarves from Dharma. For the bandannas, be sure to get
the ones with the cotton stitching, otherwise you will have white stitching
showing up on marbled work.
You will need a human helper unless someone else has come up with something
to lay the bandannas on the marbled gel. I tried making some from dowels
with pins in them like I had seen done in a book and it was too frustrating
for me to use, so I just get a person when I do them.
