Customizable handwriting worksheets are a wonderful tool for making handwriting practice more fun! Here are two great sites for making a variety of handwriting worksheets using your own vocabulary words.

The Handwriting Worksheets Wizard lets you create worksheets for printing or cursive, Zaner-Bloser or D'Nealian. You can choose the letter size and a variety of display styles. This is perfect for teachers, home school, and just general practice! (thanks Wendy)

My Moondrops also has a similar worksheet generator for print only.
