Cardmaking is the craft of hand-making greeting cards. Many people with interests in allied crafts such as scrapbooking and stamping have begun to use their skills to start making handmade cards. This has contributed to cardmaking becoming a popular hobby.

Traditional high street stores have begun to devote an increasing amount of their floorspace to handmade cards.^{[citation needed]} Handmade products are now being seen by retailers as a way to increase margins, and handmade cards are no exception. This is particularly the case as mass-produced printed greeting cards have been faced with competition from electronic greeting cards. Over seven billion greeting cards were sent in the US alone last year; greeting cards are a multi-billion-dollar business.

In contrast, hundreds of small businesses have been set up by avid crafters keen to make a return on their cardmaking efforts. Many of these are taking advantage of the low setup costs of web-based selling and the wide customer-base of auction sites like eBay. Many others continue to sell their creations at craft fairs, markets and fêtes. Others use their cardmaking skills to turn a profit in the wedding planning market making handmade wedding invitations and favors.
