If you have kids, consider using bookplates on their activity books.
You can make some book name tags using themes that your children love the most and incorporating that into your bookplate design.
If your child really enjoys trucks and cars you could make some cars and trucks bookplates and place them on coloring books, scrapbooks, all of your kids crafts and their reading books.
Using labels or even a piece of paper for your book plate label, you can make a Lil Blue Car book name tag, or a Monster Truck book name tag, or even a Towtruck book name tag and place them on the inside front cover of your child's Monster Truck books. Books are special to kids and encouraging them to read is most important.
Are you a school teacher or a home school teacher? When you want to label a school text with class information consider using classroom book labels with the name of the subject on it and your school logo on the set of personalized bookplates.
