This is a relatively simple build. I couldn’t find any 1x1x2 bricks in an assortment of colors, so I designed this necklace with all 1x1x1s (just gluing them together to get the effect of 1x1x2s). However, for a longer necklace this can be done in an assortment of colors with 1x1x3s.
2 x 4255413 BRICK 1X1 - Earth Blue
10 x 300523 BRICK 1X1 - Bright Blue
6 x 4179830 BRICK 1X1 - Medium Blue
In addition to the Lego bricks listed below you will need 5 2mm end springs, jewelry cord and krazy glue.
