My drinkware is primarily focused on classic shapes that feel good in your hands. My smallest cups and mini-mugs are approximately 6-7 0z and my regular large mugs are approximately 16-18 oz, with a range of sizes in-between. Most of my mugs can be found at Orcas Island Pottery— they can be reached at 360-376-2813 or orcaspots@rockisland.com (no online shop).
