This font was created for the letters to fit the ledger lines rather than taking a previously created font and squishing it or shifting ledger lines to make it fit. It was also designed to look like Latin lettering as children first learn to write them.
Free to use for personal and NFPO. If you want to create penmanship worksheets or other projects for sale/commercial advertising, you can purchase the Penmanship font family on my website (or TeachersPayTeachers.com). Family includes a basic lettering and tracing dot version.
Spacebar creates a blank space. Using underscore (_) instead adds space and connects the ledger lines. It will probably freak out your spellcheck, but will look correct.
