Once you've made your purchases, you can sit down at the fully stocked $5-an-hour "paper bar" and stamp, cut, punch, rip and paste 'til the trees are gone. Whether you're making one big Valentine or 20 party invites, you'll end up with something totally your own, and best of all, you don't have to store all those rubber stamps and interesting scraps of paper in your own damn house. Hours are unusual, so check the Web site before you go. We hold no responsibility for paper cuts.
