So here is a clever little idea I have come up with to display ATC's. I just put a magnet on a rigid card holder and wahla...a great magnet. I love collecting them and have so many cool ones so this way I can hang them anywhere a magnet works. I just put them in the etsy shop and bonus...you get a free ATC in it plus an extra with any purchase! Only $5 and available on etsy or lots more in the store.
