Monogramed cookies
Hi,
Here is some help. First visit this site for info on Royal icing.

Then find a font you want to use and print out the monogram as you want it to look and in the size you intend to use. Make lots of these, they are your practice sheets.
Make a batch of the icing and using a pastry bag with a very small tip, practice writing the monogram on the paper right over the printed one. Keep doing this until you can do it without "following the lines".
Now you are ready to go. Bake your cookies and have fun! Good Luck!
