How to keep labels straight?

[Derailed82]

So me and a buddy are thinking of brewing up our own products and we want to do labels as well, but I'm a bit OCD and want the labels to be as even as possible. I'm wondering if anyone here has made or purchased any kind of device to apply labels uniformly? Thanks

I line my vial up as straight as possible with the bottom of my countertop, and then line the label with the countertop and apply. I get them pretty straight most of the time.
