To help save on resources I started designing my handouts as 1/4 sheets (4 to a printed page). That way if someone didn't like them and threw them away it wasn't so bad. Also, when in leadership positions I suggested that all of us design handouts in this way so they could all be consistently sized to save.
Second, I put them on a ring. And for a lack of creativity I called it my Ring Thing. It stuck. I've been doing this size for years and it's been very helpful.
(As a bonus, I've found that it helps the YW (or kids for seminary) re-teach a principle.)
If you have any Nestie thoughts about this, let us know.
