It looks like you've used June Tailor fabric for your printing. I've never used that brand but perhaps it's the fabric you are using. I've always used 'Printed Treasures' by Milliken. They are cotton fabric sheets on paper that you peel off once it's printed. I've seen it at JoAnns and I've gotten some great pictures with it. I always print on regular paper to see if I'll like it and then print on the fabric. Several years ago I put some pictures on the back of a quilt I made for my DGS and I know my daughter has washed it many times. The pictures are still bright and pretty clear.
It really shouldn't be this stressful.
