There is a great thread on this whole subject here and even has instructions. Those pots are made out of landscape fabric, and they have a fuzzy side. The fabric is NOT cheap!! Depending on how many you need, you might want to just buy the pots from them or other manufacturers.

You could google, RootMaker, Treepots, Groove Tube Growing System.

Here is a link that might be useful: Thread on Fabric Containers

DesertDance,

Thanks for pointing me to that thread.

I do plan to buy from the manufacturer and that's mostly what I'll do.

It's just that there are some sizes and shapes that they don't make that I would like to have. For these custom sizes and shapes, the numbers involved are small so it's probably not cost-effective to have them make these as a custom order.

Thanks again!

Automakers need to stay alert to compete in a worldwide industry. Staying at the top of current technology is one way automakers try to stay relevant. However, as our cars learn to do increasingly more things, they need more controls and instrumentation. Touchscreens have become commonplace as a way to handle dashboard crowding. BMW, however, is considering a different tack: smart fabrics that become touch-sensitive pads. Smart fabric may be used in future BMW models. Smart fabrics, also known as e-textiles, are fabrics woven with digital components. The fabric is made of woven flexible, and is similar to Teflon, according to C:Net. While the technology is not ground-breaking, it has been refined to a great degree in order to reliably control a range of functions. The fabric is sensitive to different types of touches.
