In order to send homemade cards, you need envelopes. I order Envelopes wholesale online, just the right size to fit the cards into and in various colors.  It’s almost like I have my very own card store. Friends come to me when they need a great card, they tell me what they want, and I make it for them. I love doing this. It’s just a hobby, but it’s one I can do while I am working on my payed job. It fits into the laid back attitude of the office and the boss is not above asking for a card for his wife now and then.
