Carrying Items and playing them on the board.

[MunchkinMan]

Yes. You can have any number of small Items in play, whether they are Armor, Footgear, Headgear, and Hand Item. Any that you can not use must be turned sideways. The only thing you can't normally have more than one of in play are Big Items (regardless of what Item type it might be), so you can't put extra Big Items in play and turn them sideways unless you have a card that lets you have more than one (like Dwarf).
