Maybe you could suggest a trade with the fabricator for a different material that you could make use of?

Not sure how large are pieces, they can be used to set flower pots on them etc. I brought some home for my wife from a job site and she used in her flower garden as decoration. However they are small, random pieces.

A coffee table or table on a wrought iron base for the patio

I used some of the marble left over from our fireplace surround as follows:

I had them make a pedestal for my sculpture

I used some for a counter in DH's study that had built-in cabinets

I used some to make slide out shelves built into our bookcase that flanks our sofa in the library so guests will have a place to put drinks.

GF is using leftover slab remnant from her kitchen for the vanity top in her powder room.

Man Coasters.

We have a set and as promised, they never, ever stick to the bottom of a wet glass!

Keep a few pieces to experiment: rehoning & sealing.

Thank you for all of the ideas! These are great. I will definitely be saving a couple of scraps for when it comes time to replace the perimeter counters to make matching an easier task.

I have repeated dreams of marble window ledges....

I dream of window ledges too, but in my existing space it doesn't really make sense. I only have one ledge, it is at floor level. I also can't afford to remove the existing ledge and replace it. As very few people would see it on the floor, not something for me to save for.

A GW had their GC surprise them with a custom doggie water/food bowl using the remnants. I think I've also see them be made into cake or candle stands.

We tried to think of things to do with the leftover remnants, and found that the polishing and cutting charges were so absurd that it didn't make any sense. Like, we contemplated having a small tabletop cut for a small side table stand we already had, but it was going to be $300. You can go on the internet and buy a pre-cut table top slab for that much. Or for that matter, go to West elm or wherever, and buy a side table with marble slab for $200.

Sell it on craigslist.

I saw a craft project in a magazine that made tables out of copper plumbing pipe and connectors, seemed pretty easy -- that would look good with a marble top.

I had a custom table top made --- there are plenty of suitable bases around. Even a small bistro table on a cast iron base can be quite useful, indoors or out.
