Gothic Textura Quadrata is an absolutely gorgeous script, dense and architectural it is a wonderful example of how letters can be art in their own right. It's also very difficult to write well, especially for a beginner. There are two details about this variant of gothic that are extremely important to get right: perfectly vertical strokes and precise spacing between those strokes. Oddly, the calligraphy books I've read focus on how to draw each letter with the minimum number of strokes. Their method helps write faster, but it is harder to be precise and get those critical details right.
For a beginner, that can make this script extremely frustrating. So I'd like to present alternate instructions for drawing Gothic lettering, hopefully making this script easier to learn for the beginning calligrapher.
