• Look before you leap.
• Plan ahead.
• Count the cost.
• Think before you act.
• Measure twice, cut once. As you will notice from the envelope art above, I have modified that saying to “measure three times.” That comes from my own experience in working with wood for crafts!

The point being, be careful not to jump into something before making sure it is a wise move.

Use an accurate measuring tool. When the measurement is correct, move forward!
