Its been a while since I've done any card making :( But I can gain loads of inspiration from Sweet and Sassy cards @Etsy. She has a good selection of cards, and tags for both personal and business. There's even special occasion cards, I especially like these:
Christmas is coming up and everyone needs cards to send out to family and friends. This 3 card set is so pretty you may not want to write in them! You can always use a piece of parchment to put a note on and place it inside the card, and hopefully the receiver will re-gift it! I know I would!
