First time making stickers

I made a little pixel art piece and got it printed as stickers. I messed up so the edges were jagged because of the way I cropped the final copy. I realized there was a better way, but I had already approved it at that point, so there was no going back. But the stickers are so cute despite my mistakes! On their end, everything was perfect. Wonderful service. Lovely and good quality stickers! They even gave me a coupon for my own mess-up.
