That's taken fairly close to my house. When I took it, I remember thinking "I hope that pretty pink shows well."
I also recently got a suite of applications that included one called Paint It (affiliate link). Fairly inexpensive as a standalone product, just over 20 dollars from Amazon. It is a program I thought my daughter would like. It only does one thing, but it does that one thing fairly well. It creates painting effects of your photos. Running this photo through the application turned out pretty, and also fairly well got rid of that street lamp in the background without me fussing with it. It has 10 different effects and I like all of them except the pen drawing. That one doesn't pick up enough detail. The first image below using the detailed watercolor effect, the second uses my favorite effect, illustration.
I thought the first one looked like a pretty card image, so I put it on a card!
300 ppi, click the images to download the full sized versions.
The card measures 3.5 wide by 5 inches tall. The envelope is just over 5 inches wide and 3.5 inches tall, which makes it an okay size for mailing.Print the envelope on paper, and the card on card stock. Here's the blank templates to design your own. Gif format, so you'll have to increase color depth, the envelope is horizontally oriented for designing, so print on landscape settings or rotate it 90 degrees to print. Pixel drawn, 300 ppi.
