A2 Envelopes & Font

[David Battle]

Does anyone know how to print on A2 envelopes? I was trying to save money on marketing by doing it myself but I can't get Microsoft Office to print on the envelopes. It says that it doesn't meet the minimum size requirements. 

Also what's a good site to create your own font? I was trying to write the letters out by hand until I realized I couldn't read my writing (thanks to technology). Does anyone have any suggestions to make this process simpler?

Thank You In Advance
