To have some semblance of precision (in other words, to look like you have your you-know-what together), you may want to place this lucite ruler set within reach of your desk. The lucite offers a clear view to get those lines and shapes just right, and the heft of each will feel nice on paper and in the hands (and they’ll look nice even when you’re not using them).
