It's funny that you posted this now. (Well, yesterday).
I just (today) found a gallon jug of school glue that I bought last year when school supplies were on sale. I intended to try this technique.
But I was just thinkin'....
Isn't this glue washable? Why doesn't it all just wash away when it goes into a dye bath or when wet dye is applied? I mean before you want it to wash away?
And yes....you're right. It has been sitting around that long. Good intentions
