There is an increasing number of online craft marketplaces, such as Etsy, Amazon's Handmade, Artfire, and many other specialist sites. Selling online is a viable proposition for anyone with access to the internet. No technical skills are required to set up an online store within these online handmade marketplaces. Starting a store on Etsy is relatively quick and easy to do. But, you will need to work hard at taking top-notch photos of your cards, crafting superb product descriptions, and learning about search engine optimization and keywords to really get your online business off the ground. Don't worry if this sounds daunting, the Etsy seller's handbook is a fabulous source of information and will help you get started.
Much of the information we learn from investigations can’t be shared with the larger community out of respect for the privacy of the seller being investigated, so there is a natural divergence between what the community sees when they report a seller and what we see as we go deeper on the case. … [T]here are times when available public evidence suggests that a violation of our policy is clear, and our investigations find that it’s actually not the case.
The presentation of the cards—the packaging—helps make a successful handmade card business. A card that is neatly presented in a cellophane envelope looks more professional and can command a higher price than one that is unpackaged. Presenting cards in some form of packaging stops cards from becoming dirty or dog-eared and it also gives the ideal opportunity for further marketing. A label on the back with your phone number or website address could help you solicit further orders. Remember to consider shipping and packaging when factoring the costs per unit in your pricing formula.
