I've used several different fabric sheets for memory quilts and wasn't satisfied with the quality of the picture. I recently made an anniversary quilt for my son and daughter-in-law and had good results with fabric sheets from Electric Quilt. The sheets feed through your printer and can be sewn into the quilt like any fabric. Follow the directions that come with the fabric sheets. They have several grades of fabric and I chose the mid-price cotton.
Here are a couple of pictures of the quilt to give you an idea.
