The cardboard we use is a high-quality cardboard, so we don't use any coating. Tha cardboard can bear heat up to 260 degrees Celsius.

Hi Amy~ I was wondering the same thing! I'm glad you asked. I hope Sylvn lets us know :)

YeeAAA, Amy! Sylyn did answer! :) And thank you for letting us know. I can say both my husband and I are in awe at your creativity and work. The shadows your creations throw are fantastic. I'm sure you are out of our price range; BUT... When we are able to afford your beautiful art, I will come back to you. I've starred your page under my bookmarks. Just so I won't forget. Thank you for sharing your art with us. Take Care and hopefully, within the next 2 years, you will be hearing back from me. Thanks Amy for asking! I hope both of you have a great day! Until next time, Julie :) :)
