I kept meaning to post this as I get asked a LOT where to get vellum now that I seem to be using it all the time LOL!
CCDesigns is now carrying vellum in 2 weights - a lighter weight version HERE that is so fine and delicate - I use that to make die cut flowers like in this card:
I choose the lighter weight version when I want to make things like the flowers, or when I want a bit more transparency as it's easier to see through than the heavier weight version.
The heavier weight version HERE is a bit more sturdy and is my go-to choice for vellum:
I hope this helps you guys out that have been asking! :)
