Choose the theme for your worksheet. If you will be making a letter worksheet, for example, choose words and pictures that relate to the letter.
Look online or in a workbook to see if there is one you can copy, without having to make it up yourself. There are many online resources that allow you to custom-design your own worksheets for your students.
Create the worksheet by first using a pencil and a ruler to design the worksheet and then going over the worksheet with a bold black marker. You can also use a large font in a word processing program and print it out in very bold ink.
Make copies of the worksheet for your students.
