Select the desired font in your word processing program, or use a font from the resources at the end of this article. Simple fonts are best, as they are easier to cut out and trace.
Enlarge the font to the desired size. Type the entire alphabet, using lower- and upper-case letters, to make templates for children to use. If you only need letters for a specific message, type the desired message as you'd like it to appear on your poster, banner or ad.
Print out the letters on cardstock. If your printer is prone to jamming with thicker paper, print the letters on printer paper, cut them out and trace them onto cardstock.
Place the cardstock on a mat-cutting board and cut out the letters with a craft knife. If making negative stencils or templates for children to trace, save the cut-out letters. If making stencils to paint on to make colored letters, save the outline around the letter.
