I'm looking into the possibility of ordering custom vellum sticky notes and would love some more details about the writing surface. Specifically, I'd like to know how well the vellum performs with different writing instruments. Is it primarily designed for use with pens, or can pencils also be used effectively? Additionally, if you could provide any information on the best types of inks or leads that work without smudging or bleeding, that would be super helpful. I want to ensure that whatever I choose will provide a smooth writing experience for my needs. Looking forward to your insights!
