Perhaps we are not understanding this question?

Wildly guessing you're in Rhode Island with its nautical heritage, (and where I was fortunate to be at the 1963 and 1964 Newport Folk Festivals) start by Googling decorative boat anchors. Or, look locally at marine supply and marine salvage.

Come on, Ink - outside the box. If one can edge a flower bed with upended blue bottles or chiclet rocks, anchors linked by chain swags (maybe even painted all white) could make a statement. Maybe not in Kansas.

Is this at all what you're looking for?

Also Google "nautical anchor garden decor," "nautical anchor garden fence," "nautical anchor garden edging," "nautical anchor garden ideas," etc.

Exactly I did see these but not favorable to plastic. I may be asking too much

I'm working on a property that has giant cleats from a steamship, a couple of anchors, and several big chains welded so that they act as bollards. This is not an unusual theme in our part of the world. ... sorry, they want to keep them.

Isn't this different though Andrew? Derek Jarman made his garden from objects found on the beach and I have seen this done to good effect in British Columbia but this a request to bypass that and buy on the web.

Different strokes for different folks. I'm not into the nautical theme, but who am I to judge?
