I got 3 4 5 6 of these done this weekend. All are with copper wire. The rings are 16 or 20 guage and the branches are I think 26 maybe? I will have to look at the package if I still have it.
Grandma’s Tree (the leaf beads are from the large stash of bead I inherited from my Grandmother)

Fall Tree (sead beads from swap and drop circles from Grandma)

Cherry Blossom Tree (pink pearls from Grandma, green bicones from friend)

===Edit to add one more===
Apple Tree (remainder of tiny leaf beads from Grandma, seed beads from stash)

===Edit *again* to add two more===
Peach Tree (seed beads from swap, coral/peach beads from stash)

Lemon Tree (random stash beads)
