Slimline cards are all the rage right now. Slimline cards are usually about 3 1/2" x 8 1/2" in size and can be mailed in a no. 10 business envelope. (My usual A2 cards are 4 1/4" x 5 1/2") The advantage of these larger cards is that you can showcase some of the beautiful papers that are available, but it allows for larger stamps and the inside gives the sender much more room to write a personal message. I made a number of them with gnomes for my own personal Christmas cards, and they were so much fun! And although I do send out one of "those" holiday letters, I had a lot more space inside to personalize my message to each person. They are harder to showcase on the website. Probably the larger size makes it difficult to fit the image in the space allotted. But do consider them as an alternative to the A2 card.
