good quality muslin is wonderful too use for fabric dyeing- over the years I have dyed bolts and bolts of bleached and natural muslins- I've Batik*d* them, screen printed them, over dyed, gradiated, tie dyed...it is a wonderful- go to fabric for dyeing. just prewash them to make sure all oils, sizing, chemicals have been removed (detergent- no fabric softener) then dye them according to the instructions for the dye/process you are using.
