I recently moved into a new apartment and decided to retire my old corkboard jewelry display when I found these unused Halloween decorations in storage. They are thick styrofoam, and push pins stay in that material very well.
I also made a new display for some of my earrings... I'll post that soon.
P.S. Sorry for the quality of these pics, my phone was being silly yesterday.
Cool way to reuse your vitamin bottle lids!
