Fabulous work Jeanne!
Donald, boy, are you brave, just jumping in like this! I hope you checked out that eBay link.
I used to make macrame plant hangers also. I don't remember how to do the measurements between knots either. I USED to have a craft book that did tell you how to do it for any size pot. Alas, I don't remember the name of it.
I know you said you want to keep your designs simple, but take a look at Jeannes' designs again, they are very sturdy as well as being beautiful!
You have big containers! You need a
bigger knotted "cradle" to hold your pots safely. I guess what I'm trying to say is, try to run down some old macrame craftbooks. There were a lot of books that specialized in just plant hangers. There is a bead store called Shipwreck beads that had a stash of old macrame craftbooks from the seventies everything from jewelry to wall hangings to plant hangers. It might be worth your while to check it out.
Keep us posted on your endeavours!
