Bazzill cardstocks are basically the best card stocks in me opinion. A very good runner up are the cardstocks from DCWV. But Bazzill sells them per sheet and in many many many colours. They come in textured and non textured style. Here they sell both 12"x12" and port folio sizes.
I like bazzill very much but I like to use it with plain, lighter card stocks for layering on cards and scrapping. It's fun to have some textures with flat card stocks, gives a nice look that I like. So I like it but it's not all I use
I pretty much use nothing but Bazzill paper for solid cs. The only time I don't use it is when I'm making a white or black mat for a photo. That's when I use regular cardstock from HL or somewhere. To me, the thickness, the textures and the saturation and range of colors are perfect in Bazzill, where I've found them inconsistent in other brands.
