Thanks for sharing, Avery! I agree that enchanting a pen (or a brush, knife, etc) is a key stage in the path of the Art Witch 🎨!
I think that spell looks perfect from a craft perspective. Here’s a chant you can add:
Place the pen on your altar. Hold your palms a few inches above them and say:
"I cast off all negativity that may hinder my art.
I bless these tools to call forth my will.
Tools of power, tools of art
Tools that see the hidden heart
Tools that tell the path before
Be you blessed by ancient lore"
If you have a clean cloth, wrap your pen (or tool) in the cloth and let it rest on your altar. The next day, start using your pen in your creative process.
