I’m not a whiz at the drafting table, but here’s my secret for making oblique perspective drawings without a T-square and triangles. Take several digital photos of your project from different angles until you get one that matches the degree of perspective you want. Print out the photo.
Now, lay a piece of vellum or thin office paper over the photo and trace the project to create a master drawing. Add your construction notes and dimension lines, and you’re all set.
