Hi, Glad its helping.
I have a score board, its got all the different measurements for different size folds, like a5,a4,tri-fold etc,yes very useful,use it all the time
On a budget, if you can get to a craft central or like, you can fill a box with lovely, great quality a4 card for £5.99 which is fantastic value, it is lots lots cheaper than buying packs of 10 cards and envelopes. you can get various sizes of white envelopes from leading supermarkets for under a £1 usually. The pound shop is fantastic for card toppers! And if not stretching the budget too much, try and get a black stazon, it waterproof & you can use it on all your stamps, which saves buying lots of coloured ink pads, as you can then use ordinary colouring pencils and pens which cant be again bought very cheaply, I use a pack of pencils that cost 11pxxx
