Playing items that are not usable at this time to the table.

[Clipper]

Yes, you can do that with Items you can't use. So if you are already wearing Footgear, feel free to play another pair of Footgear sideways. You can't play a second Big Item sideways, though, as the Big restriction, unlike others, tells you that you can only carry one Big Item. If you already have a Big Item on the table, either used (upright) or unused (sideways), you can't play a second one in either orientation, unless you are a Dwarf, Cheat! card or another way to carry more Big Items.

You can switch Items between being used and unused at any time that you are not in combat.
