A little help please, I have a 3" wide x 3.5" tall piece of embroidery that will go on the upper back, just below the neckline. It is almost like a patch, It will be stitched on sweatshirts. Because the density is so great should I be increasing the thickness of the backing? Or should I be using two layers of 2.2 oz.? I'm afraid it will pucker after washings.
Thanks for the help.
Matt
