I found this DIY for flexible vines. Maybe someday we'll give is a try.
I also found a video for making DIY vines:

DIY flexible vines
by unknown author in 2015.
You'll need:
Aquarium safe silicone (GE 1 Windows and Doors is usually used. Use clear, brown or black. Black or brown is actually best if you can get it.)
Peat moss, or coconut coir (fiber) (not sphagnum moss), screened. Keep the fines and discard the big chunks.
A large tray
Stainless steel wire (I use this one:

Step 1.
Pour a generous layer of your screened peat moss into your tray. Cut your desired length of wire and lay it down flat, in a whirl shape if a long length is used, in the tray.
Step 2.
For thin vines, cut a smaller bead on your silicone cartridge nozzle. If larger vines are desired, cut a larger bead. Pipe a solid, uniform (as much as possible) line over your wire. Your silicone should be fresh, and not past the expiration date or you'll run into problems. It'll be too dry and too thick to be able to work well.
Step 3.
Brush the peat over your silicone. Cover it entirely, and then shake the tray gently to uncover it.
Gently, lift and flip your vine. Now place it down flat and gently push down on the wire anywhere it's exposed so that it becomes imbedded in the middle of your silicone.
Again, brush peat over your silicone. Now pat it down so that peat gets imbedded better. Shake the tray and repeat as needed.
Step 4.
Allow to cure for at least 4 days. It's ready to use. Gently bend where needed. If you're rough with it, it'll crack.
