Natalie - thanks for the stroller tag (I added the name myself so as not to bother you):
I printed these at Staples using card stock and then punched two holes in the top and plan on using plastic electrical ties to attach it to the stroller. (That way, one has to use a knife or scissors to remove the tag!)
I also printed 4 to a page to use as luggage tags. I made a second page with the street and city/state/zip, cut into 4s then had all 4 images laminated onto card stock for the luggage tags. (Just be sure to cut between each of the 4 images before you put them all on the same page for lamination or you'll end up wasting a lamination page!)
