a half inch matters
For those making standard 4.25x5.5 cards, this paper is a rip-off. The dimensions are short a half inch each way, which means that either you have to adjust your pattern or that you waste about 1/3 of each sheet when cutting a 8.5x5.5 piece to fold into a standard card.
Does give the dimensions on the front, but should be in big bold letters that THIS PAPER IS SMALLER THAN YOU'RE USED TO AND YOU CAN'T CUT IT IN HALF TO MAKE 2 CARDS.
To me, this seems a bit cheap and a way to get people to buy more paper than thery need. I'm going back to the other brands that stick with the standard letter size paper.
