This design is a near duplicate of the Cross Crosslet. If you’re good at drawing those, you’ll have no trouble with this.
Here’s an easy way to draw a Cross Fitchee:
|Start off by drawing a Cross Crosslet, but draw the bottom arm only lightly and without any buds.|
|Place a mark in the center of the lower arm’s bottom edge.|
|Now just connect that mark to the rest of the design to finish the pointed end of the Cross Fitchee.|
