The vector paths created in the previous step were not made using a de-facto shirt pattern in order to make them as easily scalable and widely applicable as possible. Therefore, in order to resize the paths downloaded in the previous step, you only need to make 2 measurements and do just a tennsy bit of math. Don't worry about being super duper precise with the measurements, the patterns are designed to be a bit big, then trimmed down to size once they are on the garment.

First, measure the width of the shirt from side seam to side seam (see image below), and write that down. If your shirt doesn't have side seams, lay your shirt out as flat as possible and measure its width. If you shirt has curved side seams, measure the longest width (should be just below the arms), and the shortest width (should be right by your belly), then average the results. This will be the "width" in the math bits below.

Next, measure the height of your shirt. Measure from the absolute bottom of the shirt (like where your legs come out of it) to halfway down one of the shoulder seams (see image below...the shoulder seam is tough to see so I outlined part of it in red). Write this number down. This will be the "height" in the math bits below.

Now for the math. The patterns I provided are sized for a shirt that is 24" in width and 26" in height. Therefore, if your shirt is only 22" wide, you should make the width of the patterns (22/24) of their original size. You can use a bunch of different proggies to do this (if you don't have one, try the

GIMP. Its free, and available for any platform!).

Now, do the same thing for the height. If your measured height is only 21", then you need to make the patterns only (21/26) of their original size.

Make sure to get enough leather to make your outfit when buying materials - realize there is a fair amount of wasteage here. I used ~1.5 yards to make my shirt using the 24" x 26" patterns.

At this point, you should have some .dxf vector paths that fit your favorite shirt primed and ready to rip on the laser. Check? Let's start the cuttage!
