Measurements: 3" x 2.25". Handmade by Betsy Grahm Olive and black patterned tumbler cup. Betsy's work is formed using various hand-building techniques, resulting in pieces that are whimsical and organic. The white stoneware clay provides a clean background for hand-painted patterns created with underglazes. Betsy's influences include art-deco patterns, the natural world, and her grandmother's quilts. With over 25 years of experience working with clay, Betsy hopes her pieces will bring a sense of joy and beauty to their users. All work is food-safe, microwave-safe, and dishwasher-safe.
