To do this, all you have to do is make a template on a folded piece of paper & cut it out...
you'll end up with something like this (I was going for the baby bib look).
Then trace it onto the back of scrapbook paper (which I used), cardstock, or whatever else you want, and cut it out.
Next, cut on a slant into the hole so it's easy to place onto the closet pole.
Lastly, with a marker, organize away (I decided to go with a yellow theme to give my blue closet a bit of a colour-punch).
Then hang, and get giddy over all the little-person clothing that's filling the closet (and do a happy dance like I did ;)
Hope you are having a marvelous day!
