I saw this and other videos from CraftStickBending.com and was quite astounded. He presents a super simple, yet really effective way to bend wood.
I have not tested this method out myself yet, but I will soon. It take very little prep or materials. All you have to do is soak the wood sticks for a couple days, bend them around a shape, and let it dry. He mentioned putting it on some low heat while drying.
My only question at this point is whether or not it reduces the strength of a popsicle stick. I’m not sure at this point.
