Sequins are a really cool kind of decoration that kids can use to make things, especially if they have a craft or sewing hobby.  Some ways to make things with sequins include:
-Using the sequins to create a background for a piece of art (e.g. a mural),
-Alternating or attaching sequins onto fabric to create new items, like curtains, tablecloths, shirts, dresses, etc.,
-Sequins sometimes called “jewels” can't always be seen with the eye, and can be used in ways that require kids to use their imagination to find them, so they can make pretend cups or other pretend “treasures”,
-Kids can also use the sequins to make a collage of designs, and use the shapes and colors of the sequins in an interesting way.

Hopefully these craft ideas give you some inspiration for your kids!

Perfect!  One of my favorite crafts that kids can do with glitter is to make earrings.  You can use simple earring wires or packaging twist-ties to create fun earrings made of sequins.  Here’s one simple idea -- the kids can draw a decoration on strips of paper, then use the strips to create a piece of jewelry that reflects their drawing.  Another fun idea is to create a glittery necklace by gluing a string to a piece of cardboard, and then gluing sequins onto the cardboard strand.  You can either glue on regular sequins, or if you have shinier ones that don’t stick, you can use a glue stick to coat them with glue like glue dots.  Here are some fun instructions that get kids started using sequins:
