One of items on the preschool to-do list is to label every thing. So based on the recommendations of my neighborhood mamas, I decided to try Oliver's Labels. I ordered the Stick-eez clothing labels (size 7/8" x 7/16"). I've stuck them onto the back of Peanut's clothing tags (so as not to cause skin irritation) and they've been through a couple washes with no problems yet. It's only been a week or so, but so far so good!
