Beth,
The fabric I was printing, was with the Inklingo piecing shapes, so they were on the back of the fabric and it won't matter if they wash off, now the bag is made up (see on my profile bright green & reddish batiks).
I do have some samples of starched & printed fabric for checking for washability, but they are in a safe place at the moment, waiting to be washed
. One is starched from one side, and another from both sides. I will try and remember to post my results, when I find them.
