I am a hand dyer and Synthrapol is great to wash with if you have any doubt about a fabric. I use it to wash any hand dye or batik that I buy. Just remember a little (1 tsp per load) goes a LONG way. Shrinkage is a great topic, but not washing also runs a risk of the color running. Also, the sizing applied to all commercial fabrics will dull your rotary cutter blade if it is not washed off first. Just a side note too: when you do pre-wash, when you dry, don't use dryer sheets - same as sizing...dulls rotary blades.
