Hi Thea
I lost my orginal photos of the process, but it was pretty simple.
Lay the clay pots on their sides and form a circle. I used a glue gun to tack them in place, then placed another ring of pots in a smaller circle on top of them. I used a smaller sized clay pot to fill the larger gaps. I think I used a more permanent type of craft glue on them once I had them all in place. I made it four years ago and it is still rock solid!
It's an awesome piece! I love it!
