First of all, I love your quilt. Fabrics that have been screen printed or used to put on a photo are going to be stiffer than milled fabrics because you are adding to the fabric inks. Minimalizing the inks without losing the photo quality is very tricky Spoonflower, from my experience does a good job. I have used inkjet fabric sheets on a number of times. They are okay but do not have the quality that Spoonflower can produce.
