What materials can I use to create faux wrought iron?

Rubber Mat - Plastic cut into strips and painted - Cardboard done the same

You might try something a bit smaller using hot glue, or sculpting paste (that one uses In Painting for dimension) create a design, just to see what works. I think you can get hot glue in different colors. Just a thought.

how about foam weatherstripping? It is super flexible and you can spray paint it black!

My pleasure..... It may also be possible to obtain a Wallpaper, but I have not seen one.

I would paint it on - look at this paint job!

Anti-Fatigue Foam Mat made out of foam when cut into strips it works well. you can heat it with a heat gun , it takes paint well on YouTube people us it to make costumes mostly. so if you can create a costume this is a good use for this. Its inexpensive and light weight but looks heavy if you create the look of metal features so get some close up image of what you want to it to look like so you can copy it. Good luck and I hope it works for you!! Teresa

Take a look at fences, garden gates, doors, and room dividers. You can buy them in different metals......paint them black. These items would be made out of lighter metals than cast iron. I wish you the best on having the ceiling you want. Please post a picture when you finish this project. You may even find these things at Habitat for Humanity or thrift stores.

Use the materials and instructions of those who make cemetery gates for their Halloween displays. They use PVC pipes and foam sheets. You can check Pinterest (and Google) for tutorials and you'll find very realistic and detailed faux wrought iron.

I found this on Hometalk, hope it helps.

Thankyou - I try............

Home supply stores can suggest something. I think they have moldable plastic.

Thank you all for your replies; will try some of your suggestions.

There are floor mats that look like wrought iron. I've seen rectangular and semi circular. Could you put them together to get the look you want??

By now, I’m sure you’ve probably already completed your project but after reading other comments my thought is to use a yoga mat, spray paint the two sides, cut it into thin strips using a razorblade and straight edge, then spray paint the sides of the strips to finish. I have not tested the idea it yet, but I usually see plenty of used yoga mats at second hand stores for $2-3. Figured it might be worth the test for anyone else who would like to give it a try. I may even have to try it myself! 😁

This is a hard process. It takes blacksmiths years to prefect this. Perhaps something in a material that easier to work with but after painting gives the same look.

Is there a type of caulking that dies to a hard finish. With some very steady hands you could possibly recreate the pattern.

Going with a lighter weight material would also be a huge benefit.

Here is a site that uses empty toilet paper rolls and spray paint to achieve this effect.
