There are plenty of ways you could. Bearded dragons are some of. Web in same way you can decorate your home walls or something else :) my idea was to make 2 pieces and put them together like a puzzle.
Diy home terrarium foam background
Diy styrofoam terrarium background
Diy spray foam terrarium background
Bearded Dragon Diy Desert Terrarium Background
Instead of a plain background, use a 3d background with a desert or jungle scene to enhance the theme.
(for better handling and taking out of a terrarium).
