As you probably know by now, I suggest using plastic pockets
from photo albums for my index card sets. Below, two index cards are placed
in a double pocket cut from a photo album. Then the pocket is attached to
two long blue ribbons hanging on a wall. (The
other "helper job" cards would hang on the ribbons above or below this one.
The ribbons are draped over a hanger that's on a single wall hook.)
The little circle in the center of the pocket is to show where you can attach
one of those sticky-back hooks (add a tiny spot of glue to the back).
The "Snack Helper" would then hang his name card on the hook. Note:
I'm sure there are many other ways you could display your helper cards -- this
is just one idea.
