I have a GBC Heat Seal laminator that I purchased at OfficeMax several years ago. The laminating pouches can be purchased in many different sizes.
For this project, I used a legal-sized laminating pouch. It's important to make sure that you put enough space between the tags so that there is room to leave a margin of the laminate around each one when you cut them out. This prevents the edges from peeling. Here is my completed sheet:
As you can see in the bottom right corner, you can also laminate homemade bookmarks such as the sweet "I love you Mom" sticky note that my son left on my teacher binder one day :-) Now both the kids and I have fun bookmarks to use for our reading times!
