If you don't know German, do an internet search for a language translator. Usually, you can select what language you want to translate from and to (ie. English to German). Type in what you want the sign to say, then have the website translate it. Copy that into a word processor document and find an appropriate font that will (closely) match the German font and the appropriate scale size (you may have to do a couple of test prints). Additionally, if there is an umlaut (the two dots over a vowel in the German language), or other specialty characters, you can usually find those somewhere deep in your word processor program. Once you have everything the way you want, print it off and glue it to the styrene. I have had great success with this technique multiple times. Hope this helps!
