Cute ideas ! The octopus cake pops are the ones I want for Romain’s Under the Sea party !!!
I love the creative ideas, my twin granddaughters have their 2nd b-day this weekend, I am gonna try to craft some of your amazing craft ideas, bubbleguppies is what they wanted! It looks like you use plastic sheets of some type of material to trim around the bottom of the jelly fish?
On the Jelly fish…I bought a few of the Chinese latterns like above but they require the metal stretchers to make the ball form….if I cut them like yours how do I keep the shape without it? Does the weight of the added tentacles make it hold shape without the metal hangers? These are for my daughters Sweet 16..Under the Sea party.
I just love the jellyfish! What a fun idea that is simple to make. Even little ones can help with making them. Thanks for sharing!
