I am a dcwv junkie... and when I don't buy dcwv i still buy paper packs. I'm not a "by the sheet" paper buyer. I probably do have more than I'll ever use in my life. LOL But at the same time.. it's kinda nice to have 3 of the same pattern and a lot of one theme when you have BIG album projects or multiple of the same thing as gifts or something, kwim?
I personally love dcwv stacks and just don't have the decision making skills that I see as neccessary in buying paper by the sheet... so i get stacks. Plus, it makes mixing and matching A LOT easier!!! And you still have options, I have found.
