What Do You Use for Lettering?

I've started getting requests for lettering similar to the standard red heart tattoo and banner with MOM on it. Most of the time the lettering has to be really small...1/4 inch high or less to fit on the banner. I find it really hard to do with even the tiniest brush. Is there a secret to this? I find myself wishing there was a face paint Sharpie!

Tiny flat brush works the best for me.

The flat brush is awesome because you can use the tips like a stamp for block letters.

Depends... calligraphy and block letters a small angle or flat, script #2 round or small liner.

Thanks, I'll give your suggestions some practice.
