Vellum is like a thicker tracing paper – but better. It’s clearer to see through, so if you need to re-draw something a few times, the drawing underneath is more visible.
It also works beautifully for vellum overlays in a Bible – words can be seen through it easily.
This package is 50 sheets – a good amount for the price. Packaging may or may not look as pictured; in ordering it several times, sometimes it’s black plastic, other times this clear packaging. Same product.
