Help!?
What can we use if we can't find glass jars or an LED light string?
If you can't find glass jars or a battery LED string, use clean clear plastic food containers or cut-down plastic bottles and battery-operated tealight candles or a small string of Christmas lights with the battery pack kept outside the container just like the instructions say.
Why does my decorated paper curl or fall away from the jar, and how can I fix it?
If the paper curls or won't stay flat against the glass, make sure the jar is completely dry (step 3), trim the rectangle slightly narrower (step 4), and press or tape the top edge inside the jar rim when you slide it in (step 6).
How can I adapt this project for younger children or older kids?
For younger kids have an adult wash and dry jars and pre-cut the paper rectangles (steps 2–4) and let them stick stickers (step 5), while older kids can design complex scenes, measure and cut twine themselves and arrange multiple battery packs for a longer garland (steps 4, 5, 11).
How can we make the lantern garland more creative or durable?
To personalize and strengthen the jars, layer translucent tissue paper or colored cellophane over your decorated paper before sliding it in (step 6), use multi-color LED strings (step 7), and add small name tags or charms to each twine loop (step 11).
