Stamphappy1650, that's a great idea!
Another tip is to score the entire sheet of cardstock before you cut, and you only need to score once. Seems so simple, but I learned it here a couple of years ago.
And I do make my bases ahead of time, especially with white or cream. With other colors, I will only cut a couple of sheets at a time.
Caution: You are entering an artistic zone. This is not clutter - this is creating. These are not pajamas - it's my work uniform.
