I love Neenah Solar White Crest Cardstock. It is my “go to paper” for cardmaking. My favorite place to get it is at Amazon. You get a ream of 250 sheets. I'm constantly using it for card bases so I go through it pretty quick. I like having the option of having alot on hand and not having to order every other week.

Not all Neenah cardstock is created equal. Make sure you are getting this particular version of it. Occasionally you can get it on sale.  Check it out here to see what the current price is.
