To make something similar, you will need:
-tissue paper (I used white streamers)
Start off with a plain Styrofoam egg.
I really like it! It's nice and delicate and fits perfectly in this little crystal holder that I found. I would make more but I don't have anymore of the crystal and...well...I'm lazy.
UPDATE: I'm not as lazy as I thought. This Easter egg needed a friend, so I made another one!
