Check out a company called Van Dykes Restoration. They sell rattan and may have a video. I know you need to soak it so it is flexible.
You can buy rattan in rolls. Find a good U-tube video and copy it. Remember to soak the rattan in warm water so it shrinks after it's installed so it's tight.
Hi Kay! Here you go! Hope this information gives you some helpful information. Merry Christmas!
Wash very well then paint it white with a roller
