The Capital Stem & Compound Curve

The compound curve of the capital stem is essential to commit to muscle memory, as it fits within a significant amount of the Copperplate capital letters (with or without the comma dot to the left). You can download a drill sheet here - trace the shape until you've nailed it down, or use it to practice the remaining strokes in the capital letter, like the curves of the B.  Slip this under a translucent practice sheet, or print it on laser paper (or other ink-and-nib friendly paper).  

Remember to use the same ovular shape at the bottom and top of the compound curve that makes up stem, as shown in the photo below.  

When flipped, the curves of the capital stem mirror each other.
