That's a whole lot cheaper than I imagined! For those asking, I had a crack at a DIY heat mat today using corflute (about $8 a sheet from my local bunnings) and it came out really clean. I forgot the whole photo thing as I was testing an idea that already has a thread in general, I believe. With a picture frame type surrounding it might just be the look you're looking for
And somehow during that post I forgot to mention how great this set up looks! Can I move in and borrow the other wall? Haha
