Thanks for the response, vmrs.
I've tried several from Amazon and just haven't been happy with them. The portability is nice, but they seem, somehow, not my cup of tea. Maybe that's the problem - I keep trying to brew them? 😂😜
Anyway, I found a couple websites with calligraphy practice sheet generators. A calligrapher can design precisely what they want and download the sheet as a .pdf and print as many as they want. Here's my favorite
, but anyone interested can search for "calligraphy guideline generator" to find more.
I've also started designing my own in CorelDraw. Attached are photos of two of them for a 1.2 mm wide nib at a 3:2:3 ratio.
