Add about 1/2" of soil, a small amount of moss, then sedum or other tiny succulents to a glass bottle charm. Total dirt/moss should be about 3/4". Mist very lightly as needed to maintain; do not overwater.
Cut roughly 12" of wire. Wrap wire around the bottle approx. 3 times. Wrap wire one more time half way so that both wires are on opposite sides of the bottle. Make loops with each one of these wires for your chain. Continue to wrap the wire 2 more times and secure wire around both the existing loops before you cut off the excess wire.
If desired, use bronze wire and crystal or gemstone beads to wire wrap a beaded chain section to add to the necklace chain.
Use jump rings (or your beaded chain section) to attach the loops on the bottle to the chain. (See Jewelry Basics 101 PDF for step-by-step instructions on making wire loops and the best way to open and close jump rings.)
If desired, stamp a small metal tag using instructions in our Metal Stamping 101 (PDF). Wording suggestions for your tiny wearable garden: Grow, Inspire, Breathe, Reap what you sow, Plant dreams, Bloom, You're Beautiful, Be Still, Relax, Bounty, Gratitude, Wonder, Flourish, Dream, Hope, or Plant now, harvest later.
Gold-fill chain and phosphor bronze wire are excellent materials for a living necklace like this, as neither have a plating to wear off.
Phosphor bronze wire will naturally oxidize and darken over time. It also has superb spring qualities, high fatigue resistance, excellent formability and solderability, and high corrosion resistance.
