Card Trays. Do you use them when playing games? Or any other kind of card holder?
I used to think the idea of card trays was kind of silly. You should be able to hold a bunch of cards and fan them out and play them easily, right?
But, sometimes, if you think about it, things can get a little awkward, especially with games that come with two (or more) types of cards you have to manage. How do you hold them in your hands? Each type in a different hand? Maybe. Or, you hold them in your hand all sort of mixed together. But this can be troublesome if you get them too mixed together, and it can be a lot of cards to hold.
So, you most likely resort to separate piles and playing goes something like this: Look at one set. Put it down. Pick up the other set. Look at it. Put it down. Forget what was in the other set. Put down the current set and pick up the other set. Oh wait, I need to look at both together. Pick up the other set in your other hand. Scrunch your hands together to manipulate them. Then fumble around until you almost drop them all!
Blech! What a pain!
