A parallel rule is a thing, not an edict.
I like tools, always have. One of the great satisfactions of bookmaking are the tools I get to use. As I was making yet another Chinese Thread Book I realized that some of the fold lines I need to score could be done more easily with my parallel rule. I’ve wondered if people know about this tool.
I think my dad gave me my first parallel rule. If not, well, it’s the sort of thing he would have given me, so he gets the credit no matter what. I didn’t know this right away, but this tool is used both in navigation and in drafting.
I’ve discovered that’s it’s a really handy thing to have around when sketching interiors.
Here’s a cool thing to know about drawing things in the world: the horizontal lines for the world slope every which way, but the vertical lines remain strictly vertical. I’ve enjoyed starting some my drawings by using my parallel rule to make a vertical line in the middle of the page, then drawing parallel verticals to help define the rest of the space.
It’s just recently that I thought about using it to score parallel lines for the twist box layer of my most recent Zhen Xian Bao …
…which turned out like this.
