My daughter and I went as Mommy and Baby Jellyfish this Halloween. The glowing jellyfish costume idea was a hit. And we had comments and compliments all weekend long!
The legs/tentacles/stingers/not-sure-what-they’re called were glowing too, but you can’t see it very well in the pictures. These cost me about $28 total to make both costumes. The best part is that you can simply “take off your hat” when you’ve had enough of being a jellyfish.
I got the homemade glowing jellyfish costume ideas from another costume on this site, but made it my own. Here’s how to make them:
* Foam Board
* Bubble Wrap
* Shower Poofs
* Shredded Gift Bag Stuffing (the shiny kind to reflect light)
* Battery Powered LED Lights (You have to use LED because the regular lights get too hot and will melt your costume!)
* Netted Laundry Bag
* Glow Sticks
* Hot Glue Gun & Glue
* Clear Packing Tape
* Exacto Knife
Making the Glowing Jellyfish Costume
Take sombrero and lay it over a large piece of foam board. Trace around the sombrero to make the desired size jellyfish body you want. Cut out the circle of foam board with Exacto knife. Lay sombrero back on top and poke holes through the circle part of the sombrero that sits on your head and into the foam board to mark where to cut out the hole for your head. Cut and punch out desired hole, hot glue sombrero to foam board and pull the sombrero neck strap through hole.
Take bubble wrap and roll into tubes and hot glue or tape to top of sombrero going around the entire diameter of the hat, making something that looks like a tiered cake. Stuff shredded stuffing into crannies of bubble wrapped layers. Attach battery operated lights all over bubble wrap and stuffing (with tape) and tape battery packs to underside of hat with packing tape. Make sure you have the switches in the direction you want them in and the battery covers facing the ground in case you need to change the batteries. Also install batteries before taping.
Take the laundry bag and pull it over the bubble wrap. Stretch and secure to underside of hat with hot glue. Hot glue any loose corners of laundry bag down to make it look curved.
Take a Shower Poof/loofah and cut the center string so it becomes one long, loose string. Hot glue this around the edge of hat.
Cut ribbon to desired length and hot glue to underside of hat. You can add some shower poof strands here as well.
Let it Glow
Crack glow sticks before you go trick or treating, to your party or whatever and insert under netting on underside of hat. You can also dangle some with the ribbon and/or crack one open and poor it onto the fabric itself (legs).
Warning: cracking open glow sticks can be dangerous. Make sure eyes are protected and be prepared to smell a very toxic odor. If I would have known this beforehand, I wouldn’t have cracked any open.
Place onto head, turn on lights, and go delight your friends, neighbors and all the strangers you’ll come across! Have fun and be safe.
