At least I think this is what is doing it.
This is really good quality fabric, and was bought five months ago.
The reason I think it is the starch, is bc it is only on the 'wrong' side of fabric.
I don't like to put my iron on the 'right' side, so I press from the back.
It has been in the dark, on top of other clean fabrics, so no transfer there, and it was folded, wrong side in.
Now wondering if any of my other fabrics that I washed ahead of time and pressed, might be doing this. I sure hope not. I'm afraid to look.
If you hear loud screaming and then a thud...you'll know I looked :wink:
