For each eye image segment, hold the corresponding color of lightwire along its line to measure out the proper length, then cut it to size, adding about 6″ of extra length. Label each segment with tape to identify it, for example, “eyelash/frame 1.” Group the cut segments together by frame: common or 1–4.
For elements like the eyelashes, which are laced in and out of the board, follow the wire’s path back and forth with a piece of string, holding it along the way with bits of masking tape. Then measure the lightwire against the string and cut it to length plus 6″.
Lightwire can’t be folded or bent too tightly. For corners, use separate segments or thread a single segment out the back, loop it, and bring it back to the front at a new angle through an adjacent hole. To black out short sections, cover the wire with tape or heat-shrink.
