We buy all our labels at OnlineLabels.com. They have the most wonderful range of variety for the best price on the web. We are an Artisan Perfumery - all hand crafted perfumes, pheromones, and bath and body products. We release at least 20 new limited edition products every month thus we go through a LOT of labels, thousands every month, so we order in bulk.
Don't limit yourself to merely white labels! OnlineLabels.com also sells brown/parchment style sheets that can be used for an antiqued sepia look, which also saves you from using up all of your expensive colored ink when you try to reproduce this look on white paper. Some other tips....we always print on whole sheets, rather than separated segments. That way, we never waste sticker sheets if something doesn't line up properly. All you need is a decent paper cutter and you're set! We get 15 product labels out of each sheet. Also, if you want your labels to have decorative edges, there are tons of decorative scissor/shears on the market these days (thanks to the scrap booking craze) so you can edge your labels any way you wish!
