Welcome rgreen!
I think most people here try to use existing tables.
Have you looked for something in thrift stores and goodwills
that might fit the bill. I may have seen some while surfing stained glass supply stores online. They were small ones.
But I can't for the life of me remember where.

Hazie

Here's a site I found for ya.
I'd try what hazie suggests though.. recycle!

Here is a link that might be useful: mosaic table bases

rgreen- nice to have you here. I agree with Hazie about using an old table. They tend to be the cheapest to acquire.

When you were making you stepping stones where you pouring the cement over the media?(cups,plates, etc) Or where you making them onto already made stepping stones?

If you were using the ready made stepping stones it wont be to different than what you have already done. If you have done it the other way you might want to check out some books in the library or ask specific questions so we know what your unsure of.

Your definitely at the right place to get info, opinions and ideas thats for sure!!!!

Remember...we REALLY love pics!!!!!!
