Common questions

Which side is peanut butter and which is jelly?

Brown shirt is peanut butter, purple shirt is jelly. Label the bread signs 'PB' and 'J' big enough to read from ten feet away so nobody has to ask.

How do you wear the bread signs?

Tape or string one bread sign to the front of each t-shirt like a sandwich board front panel. Two attachment points at the top corners keep it from spinning.
