My granddaughter starts kindergarten this year and she has sight words she'll need to know. We made her a set of flash cards with all 300 of her sight words for the year. I needed to get them done and shipped off so she could get a head start and they were here before I knew it. Easy to use, did a mail merge and printed them all out with minor corrections, mostly of the mea culpa variety.
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.
