These natural edge Ambrosia Maple nested bowls all have round bottoms and each was twice turned. I used the Oneway Coring system to cut the rough outs for these bowls. The largest bowl is 18” x 7” x ¼” the middle bowl is 15” x 5 ¼” x ¼” and the smallest bowl is 12” x 3 ½” x ¼”. They all have been finished with Danish oil.
