A service called MyPostcard will turn those images into greeting cards, gift cards and postcards.
Users register on the website or mobile app, select a product, choose a design or make a custom layout and send their cards. Prices at MyPostcard start at $2.29 to send a postcard anywhere in the world and $3.99 to send a folded greeting card.
Their collection of font styles look way better than my handwriting. But if you want to send hand-written notes and mail them yourself, you can order set of cards starting at $11.99.
For more details, visit the MyPostcard website and check out the apps in the iTunes App Store and the Google Play Store.
