Masterboards are one of my passions. I generally make one large masterboard using a watercolor paper canvas and then cut up the paper to make cards and other things that coordinate with one another. This is how the wine/vineyard themed masterboard was made.
This masterboard begins with a 11" by 15" piece of Strathmore 140 lb cold press watercolor paper. I use a credit card/hotel key to spread a thin layer of gesso on the paper to give it a little body and some texture, then allow it to dry. The ink I'm using is Tsukineko Kaleidacolor Vineyard 025 the newest member in the family of five-color ink pads recently released at CHA 2013 in Anaheim, CA. Delicious colors that remind me of wine: Lulu Lavender, Sweet Plum, Gray Flannel, Rich Cocoa and Bamboo Leaves. These are all Memento inks that can be activated with water.
The first thing I do with the pad is click it together. Kaleidacolor ink pads have an innovative sliding palette that slides the various colors together when you want to use it and then slides them apart when not in use. This keeps the colors from bleeding together. I run a brayer across the ink pad and then run it across my prepared paper.
