For our upcoming 90-minute library program you will need handouts and a lettering tool.
Tombow brush marker (see picture)
A good brush marker for beginners is the Tombow dual brush pen. Most of these options can be found fairly easily at a nearby local art or craft store. They can also be purchased through my favorite calligraphy source: JohnNealBooks.com
If you have a Pentel color brush or water brush and a set of watercolors, feel free to use that for the class instead of the marker.
