Something I've been seeing alot of is people posting pictures of their proud work...But the pictures come out so blurry that you can't properly show it off.
...Yet the curtains in the background that are 20 feet away are in full focus.
Here's the simple solution...Take a step away from the object you're trying to take a picture of! Unless you're specifically using a "Macro" mode, cameras usually need at least a few feet of distance in order to focus on the object properly.
Believe me, even if you have a low-resolution camera and the picture has "jaggies" when you have to enlarge it...That's still MUCH better than blurry!
And a decent, FREE program that will let you zoom into the image and crop just the part you want is Picasa:

Good luck!
