I meant to share this with you awhile ago, but I'm forgetful! I laminated this, and wrote my phone number on the bottom with a dry erase marker, that way if I have a sub, she can easily erase my number and put hers, and it's no big deal! This has come in handy many times, especially when parents are early, I do try to always be back in time...but, sometimes we just aren't! Hopefully you can get some use out of it. You should be able to just click on it to enlarge, and then right click and save as. You could color it in to make it prettier, but I like it like this!
