Assembly & Cage Bars:

To make the vertical cage bars, join Light Blue yarn to the top edge of the Lantern Bottom.
Chain 12 (or the height needed to bridge the gap between bottom and top dome while keeping the firefly suspended).
Attach with a sl st to the corresponding stitch on the Lantern Top Dome, then sl st along the dome edge to the next bar position (space them evenly with 4 bars total).
Repeat this process for all 4 vertical bars, securing the top and bottom sections together.
Using Black yarn, attach a chain of 20 to the top loop to create the hanging handle. Attach keychain hardware, a decorative wooden bead, and key charms to complete the look!
