This website is fabulous for making your own handwriting worksheets. You are able to type directly onto the worksheet as you would like it to appear on the dotted lines. I mostly use it for the children to get practice with writing their names, but you could use it for anything like practicing the letter or word of the day. Most importantly the letters appear as we would teach them and aren't in any fancy fonts that would be hard for preschoolers to distinguish.
