I completely believe that with a pattern like this, the layout is key! If it doesn't look good and balanced when even in thumbnail size, I'm going to keep working on it until it does. Second of course, is the colorway and the style of how to color (fill, no fill, outline, thicker outline...etc.), do I create custom fills, patterned backgrounds...the list is endless. I usually concentrate on my main pattern first. Once I get that "right" in my head, the companion patterns follow and flow effortlessly.
These are made from goose eggs, each one took me 5-6 hours average. The process is similar in theory to batik, each line/stroke is painted on with hot wax, from a wax pen, also called a "kistka". The eggs (hollowed out and cleaned) are dipped in a series of dye baths in progressive colors. Wax is applied after each color to basically seal in that color. At the end, the wax is taken off with a candle flame, and et voila, THE REVEAL. Each little one is kind of like a surprise, you never know what you'll get.
