One of my longest dragon decor pieces is a branch I found out on the railroad tracks by my old apartment. It was handed down to my youngest dragon and just baked in the oven for about an hour, and any subsequent cleanings it needs.
My chameleon enclosure uses branches from my maple tree outside. Those were too big for the oven so were soaked in a bleach solution for 24 hours in my tub, followed by soaking in just water for 48 hours after. At a store those pieces would probably run close to $30 a pop but were free with just a little time and effort.
