Trial and error... what app are you using to draw your prints?

Paint.NET, and thanks I guess.

For Paint.NET, you need some kind of guide for each part that will help you align the prints. You could supply a checkerboard pattern each for the torso, hips & legs. Something like these: [url]https://www.google.com/search?q=uv+checkerboard[/url]. Then upload these to Mecabricks and take a screenshot of an assembled minifig. Now if you use this as an extra guide layer for your part, you can get an idea for where things are going to line up. Also, some UV maps are easier to line up than others. For instance, the hips uv3 & 4 maps are much easier for me to align than uv2 because they're both taken with a front-on view, just like the legs and torso.

Thanks dude, helped a lot.

Great.. don't forget to switch the view to Ortho before you take the screenshot. If you have a numberpad, you can use the shortcut [Numpad 5] to toggle between Perspective and Ortho... otherwise use the View dropdown on the top toolbar. Ortho will straighten things out for the screen shot, and [Numpad 1] will move the camera to front-on.
