Am I being too ambitious?

Welcome to the forum,best site internationally as far as I'm concerned(no offense Mr Bridges)I'd also consider sealing your travertine/limestone before you staet setting to save on the chance you might stain your tile when setting,natural stone drinks like a good Englishman,also be sure to use white thinset or your sure to get headaches from your tile sucking up thinset from the bottom.Good luck.
bootsmckiber (Canada) :hurray:white thinset

:mad2: grey thinset

Also make sure you back butter tiles so that you don't get the trowel marks coming through and shading your lovely trav/limestone."Natural stone drinks like a good Englishman", no problems then.
Thank the lord it choose's not to drink like a Scotsman or it would cost you lots more:yikes:.

It is probably best you don't take the DIY route even cheap stone is an expensive mistake.

I don't believe I left out the back buttering,I don't like people standing over my shoulder when I work but if your not doing the job yourself then take about 10-15 minutes of your time to make sure your tiler is doing all that you've been told or you'll be singing the blues down the road,thanks obobsmith for covering my forgetfullness,that's just one of those things you do automatically when you've been tiling for a quarter of a century,I also forgot how you tell a well balanced Scotsman,is he the one with a drink in both hands or the one with a chip on both shoulders?Cheers,
Mike :8:

Thanks for the ongoing advice people- I've got some quotes starting to come in. Still tempted to do it myself... but the wisdom on here is hard to ignore!
