You could print the letter in that font, cut it out and use it as a template with gumpaste. Some people use the cricut machines to cut letters too.
Make a royal icing run out. Draw the letter on a piece of white paper and cover with wax paper. Go round the outline with a writing nozzle and stiff royal icing, making sure that each line or curve makes contact, and leave to dry for 24 hours. Then make some fairly loose royal icing and flood between the outline. Leave for several days to dry thoroughly before peeling off the wax paper. It's best to make more than one just in case you break it and under no circumstances put glycerine into the icing as it needs to be really hard. They look great, are totally edible and taste delicious.
