A kit will typically contain an A5 version of the main image, a sheet of decoupage/pyramage elements for you to 3D, co-ordinated backing papers or panel sections of the card, multiple message labels and a step by step instruction sheet. Many kits also contain matching envelopes. Naturally you can resize the sheets to make any sized card you like. NOTE These sheets are supplied as several JPG format files that YOU print at home (180gsm glossy photo card stock is recommended for best results). You can print them as many times as you want and make the cards again and again - or rearrange the elements of the card and make many different cards from the same kit. On receipt of payment the files are EMAILED to you in a ZIP file. (You can download Winzip here http://download.cnet.com/WinZip/3000-2250_4-10003164.html if you don't already have it.)
