How do you feel about diamonds and parallelograms?
Most of us have used squares, rectangles and triangles in our quilts, but other shapes seem to show up less frequently. Because they aren't used as often, we're less familiar with them and they can be intimidating.

All you need to cut these shapes is a rotary cutter and a ruler with angle markings. Most rulers have a 45 degree marking. Some also have 60 degree markings. For this tutorial, I'm using the 45 degree markings to cut shapes with 45 angles, but the method would be the same to cut 60 degree shapes.
|Tools and materials
Start with a fabric strip or a strip set. Your pattern should specify what width to use.
To make the first cut, line up the 45 degree marking from the ruler with one edge of the strip then cut across the strip along the edge of the ruler.

In the case of diamonds, it doesn't matter which direction the 45 degree cut lies, leaning left or right, because the diamond has four-fold symmetry. You can just rotate the cut shape 135 degrees to orient it as needed (unless you're using a directional print and care about the print direction, in which case you'll need to keep reading and pay attention to cut direction).
If you're cutting a parallelogram with two longer sides, simple rotation won't work. You can't just rotate a left-leaning parallelogram to make a mirror image leaning right instead.
You'll need to pay attention to which way your parallelogram needs to lean before you start cutting.
The pictures below show how to cut parallelograms that lean to the right as well as those that lean to the left.
