you guys may have already thought of this, but i used it when i was SM for our production of You're A Good Man, Charlie Brown! back in middle school (it was really bad looking back on it, but for a middle school play it was good, and there were lots of funny memories ). anyway, i made a diagram of our stage on the computer of what it would look like after each scene change, and printed them all out so i had a booklet. then i had all my crew members intial what they were going to move/bring out/take off before we went out, so it wasn't mass confusion in the blackout. i found this worked really well - all the scene changes went smoothly and quickly. another thing i did for that play was go through the script and right down which actors were in which scenes, and posted that on both sides of the stage (remember these were little kids...). that worked pretty well too. just some suggestions....good luck with your next performance!
