Your answers will effect the size and design of your stickers - be as specific as possible. A sticker needs to convey a message quickly, clearly, and often from a distance. Stickers are not newspaper ads. Bigger Isn't Always Better. A sticker's visual appeal and impact increases when graphics are complimented by a shape other than rectangular.
Circles often have no added cost, and any custom shape is possible with the use of a die.
A die is usually well worth the inexpensive one-time fee. Think In Reverse. Just because you are printing on white vinyl doesn't mean the background of the sticker needs to be white. For a one-color sticker use a printed color as the background and leave the copy white for a more effective and appealing image. If you are creating a promotional sticker, don't waste the white space on the back of the sticker.
