Exploring the Renaissance Tiles has been a rich and rewarding experience as the tiles nuances came to life under my fingers. Adding shading with Sepia and White Pastel Pencils is like adding cream to coffee as it adds another layer of flavor, beauty, and complexity to the artwork. The addition of Renaissance Tiles to one’s Zentangle repertoire is worth the pursuit. If you have not experimented yet, don’t wait, you will be thrilled with the results. Don’t know where to get the tiles, see Sharla’s Store link below.
