Message: I am tie dying with my daughters art teacher in 5th grade, The art teacher and I have noticed that when using green dye the area that is usually white on some of the shirts is blue. They look terrific but I must admit that we are a bit puzzled and we wondered if you could tell us why this has happened on several of the shirts ,but not all. Thanks for your help.
P.S. It happens with both the liquid and powdered dyes.

What kind of dye are you using? It makes a big difference whether you are using fiber reactive dye, or all-purpose dye, or what. (Both are available in liquid and powder forms....) What brand is it?

I strongly recommend against the use of all-purpose dye for tie-dyeing. With all-purpose dye, the shirts must be simmered for half an at 190 degrees F. for best results. It does not work at room temperature. This could be the source of your trouble - or not, if you are using decent fiber reactive dye, in which case the answer is something quite different.
