Oh definitely, But I figured if I sell the shirts I would have one available with 2 X's on the sleeves with one in front and one shirt with just the front (and maybe a bunch of variations on request), since the number of images makes the price go up. It's the difference between 15 and 23 dollars. So buttons could be added to any shirt, jacket, bag and they come 5 packs for $7. I also have a SHIELD logo ready to go but I think that's really pushing the line.
And I made a shirt based off the one Ice wears in the cartoon, I'm pretty proud of it. Still now selling it yet just in case.
