Ok, so I am testing out using soda ash to pretreat fabric to print on and ran up against some questions:
1. How much soda ash do you use per gallon?
2. Some places I have read have said NOT to iron the fabric because the soda ash could turn it brown--but I plan on attaching this fabric to freezer paper to print on. Suggestions?
3. If I have a blanket that I forgot to prewash my fabric and am concerned about the colors bleeding, could I soak the blanket in the soda ash solution, let it dry and then wash it safely?
Thanks to all those who suggested soda ash, i am really looking forward to trying this and seeing how it does!
