Bird tags and stickers

Last year I designed three bird stamps (for the "advertising and promotion" section of my diploma) and had them made up in sizes that would fit a range of tags and labels, but would also look good on a business card.
 I am a crafter, and I wanted my "business card" to look handmade, not impersonal and glossy.

The smallest owl stamp can be used on the back of my handmade origami cards, along with an email/website address stamp. I can also use them on my cards themselves, as part of a design....since stamps are quite expensive to have made up. I wanted to make sure they would be used well.
