Tutorial by designer Lynsey James - Thread-a-Bead https://www.threadabead.com/4530/1/3D-Beaded-Peyote-Ombre-Star-Ornament-Pattern-Bead-Pattern
Pattern description sells suitable for beginners & quick, 4-6 hours of beading. Hmmm several more hours for me. Maybe I take too many breaks...LOL This pattern is a challenge on a FaceBook Beading group, and a lot of experience beaders are having difficulty. Many taking several attempts to get one done...and often the rows are off, color pattern not symmetrical... This was my second attempt!
Showing the 3D structure. (1st one in progress that got ripped out due to mistakes & breaking a bead on the last section.)
