Model – Theater is a three dimensional art. Make a study model. Just for you. Build it out of dirty cardboard and used tape. The messier and more ripped it gets, the more useful. Later you’ll build the clean white (or colored) model to be used by the director in blocking and by the TD, carpenters, and painters as a guide to construction. Do be sure that if a window, for instance, will be seen through, that you build it see-through to check sight lines.
Practical pointers. Measure twice - cut once. Use a metal straightedge to cut against. If it lacks non-skid backing, add masking tape underneath. (Never cut along drafting tools as lines drawn later show every notch you cut!) Use sharp new blades. Remember Alice’s caution: “if you cut your finger very deeply with a knife, it usually bleeds.” Wash hands. Wipe off excess glue.
