Despite my hopes to use up supplies that I already own, I couldn't resist this find at Hobby Lobby. I heard through the grapevine (YouTube) that Faber-Castell sells "gelatos" for kids, and they are much cheaper than the adult version.
These are the "gel sticks."
I took these out for a test drive, and they appear to me to be the exact same product as the gelatos -- at half the price.There are fewer color choices, but still plenty to work with. Wahoo!
If you have wanted to try out gelatos, this is a less expensive way to do so. Same materials, same results. I am a happy crafter.
