I started making ACEOs a few weeks ago and now I'm totally hooked. They're so much fun to make and I've gotten some good responses from people at work whom I've showed them to. Also, since I don't really have professional business cards yet, it's kinda nice to carry them around with me and show people what I do.
I've been reading from some others that they too have a lot of fun making their ACEOs and ATCs.
For those that don't know....
I've also heard that some can fetch about $30-40 on eBay! I haven't posted them on their yet but I definitely will.
