This pattern is very easy to customize. If 100 starting chains don’t fit your needs, you can start with any other number that is divisible by 4. Put stitch markers in 4 equidistant points on your starting row. These points will be where you put your 3HDCs, and V-stitches. These stitches are important to give the proper shape and size to the body of your princess cape.
If you want to make the body of your cape longer, but you’ve already made it as big around as you want it to be, then you can quit making the 3HDCs and simply continue your V-Stitches to keep the shape.
