100lb is the perfect weight for cards. Alabaster is a nice white. It's not super bright so it is more subtle than the bright white of other producers
This is the whitest Cardstock in my stash. That is a statement since I have tried quite a bit over years of my papercrafting obsession😆
The markers I used glided on the paper. The colors looked gorgeous.
I am real impressed with this card stock. I really like it. Color is perfect.
