Make Your Own Holiday Cards with GIMP

"Pick a photo you like. It's important to have enough resolution, and that's an easy place to go wrong. People show up all the time on GIMP channels saying "I created my image as 5" by 7", but when I printed it out, it looks really fuzzy. What's wrong?"

"What's wrong is that digital images aren't measured in inches -- they're made up of tiny dots called pixels. The number of pixels in an image controls how much detail you'll get when you print it. A common rule of thumb: if you want a good looking photo, try for at least 300 pixels per inch (PPI).

"I print my cards on US-Letter sized paper (8.5" x 11"), folded over, with the card taking up half the page (Figure 1)."
