I love using the basic black cardstock! its so universal and wounderful to work with! I use it as a main background or and a mat around a photo! It matches a lot of things and its easy to add to make your pages just right! the basic black paper is a great start to a new LO or style if your stuck and want to try somthing new! Black and white also go great together!
Bazzill cardstock is the highest quality cardstock in my opinion! I love the thickness and how sturdy it is. I frequently buy packs of white, black, and kraft to have on hand. This basic black pack is cost effective for me!
