Great design for the elephant, thanks for sharing it. I made a version of it and love the design.
Thanks for sharing your image. I love the rocket design and did a variation on it.
Great project. I loved the elephant and rocket variations and did a version of those. The rocket is maple and the elephant is oak. The beads are from an extras bin at a local wood store. I finished them with Howard butcher block conditioner which I already had and is (obviously) food safe.
