Go fer it.
I will try it but I am glad you let me know about the problem ahead of time. I do have about 1/2" to 3/4" that I can cover up any cracks along the edges on the project. I will have to post what I am doing soon.
It is much easier to post what you want to do and get feedback before trying. The panels were not the least expensive material I could use.
Here are my options:
Textured wallpaper - adv least$, available, paintable dis - not alot of detail, out of scale somewhat, most easily damaged
Ceiling panel replacement - adv available, paintable, middlle of the road $ wise and durability wise, dis - cracks cracks cracks
Hirst Arts mold floor castings - adv most durable, paintable, best detail and variation dis - have to be ordered and most $ up front investment and molding material, takes alot of time to cast them
For my current project, it would be a shame not to use the 3 ceiling panels I have, but I also have a large roll of textured wallpaper.
I was at first combining the Hirst Arts molds and ceiling panels for this project. My decision can be changed after the circular saw test results are back.
