While I use the bookmark sheets successfully in play-testing HOW, (and I still love that format dearly) I decided to put my horde of index cards to work as well!
Find this new index card size Hero sheet by clicking the HOW downloads link to the right. Four are laid up on to one 8.5x11 page so it is pretty easy to get an adventuring party put together quickly and efficiently. I affix mine, using a bit of glue stick, to the back (blank side) of an index card. This leaves the lined or graph side open for further notes and use by Players. If you use white index cards and at least one other colored index card, you could designate one color for Adventurers and one color for Wizards! Simple, sensible and good gaming!
