A review for Sticker sheets by Aviv Or.
I've looked for a place to print custom-made stickers as a personal gift for a while, and nearly gave up before I found Stickermule. Not only could I easily create my own completely free-form sticker sheet, there was also the option to print only several copies for a very reasonable price, instead of a massive commercial amount.
The quality is fantastic, the delivery was surprisingly quick, and the service is wonderful. This first order made me want to create LOADS more sticker sheets =)
