Do you have a favorite paper for practicing broad edge? I like using Borden & Riley Cotton Comp. It’s semi-translucent, so you can lay a printed guideline sheet underneath. I also like using watercolor paper for when I use watercolor or gouache as ink. For finished pieces, my go-to paper is Arches Hot Press.
It’s a good idea to try different types of paper as you get more comfortable with your letter forms. I recently tried a few fine art papers such as Bugra (used above) and Arches Text Wove, and although they are a little more challenging, they have wonderful textures, which can make a good piece into a great piece.
