Last year I made a family tree quilt, we printed everyone's pictures onto the fabric sheets, this was my first try with those. When I soaked them in the water, I didn't have any problems with loosing the pictures, but the sheets shifted. I took them out of the water and laid flat on towells to air dry and they were no longer square!! The pictures were small enough no one noticed, but I had larger pictures at the bottom which I just heat set. That worked way better than the water. I even showed my Fiber Arts group the package and what happened...no one had ever seen the shifting before. I haven't tried to print on muslin, would heat setting work on that??
