Part 3 of Ralph Griswold's series on number drafting, which generates weave patterns from numbers. It explains number bases beyond 10, with alternative symbol sets for base 16 (letters and dingbats), and proposes treating strings of capital letters and the blank as base-27 numbers. The example phrase 'PLACE YOUR BETS' is converted to base 8 and base 16, and the base-8 digits are used to derive a pattern shown on the last page. It ends with references to related articles on number drafting and code drafting.
