I am a big fan of card stock for several purposes. Initially I used it for table tents for groups that have ongoing meetings. (I downloaded a table tent format that prints on both sides of the folded tent.) People are always impressed and they work perfectly. Lately I have also been using this project whenever I am printing something to go into plastic sleeves for binders or into the clear cover itself. It provides a nice clean print job and the stiffness makes "stuffing" the sleeve or binder cover a snap.
Been using Staples card stock for a while. I make my own greeting cards make posters for community events etc. Works willl with my inkjet printer. Holds and displays colors well. Easily folds in half for greeting cards.
GREAT PRODUCT with ever so many uses. I buy Staples card stock on a regular basis. I use it for my own card designs many many craft projects far too numerous to list. It is a great product that prints with good color representation that will last for years at a great price.
