I cut diamond shaped wedges from cedar shims and used them along with double sided foam tape to join pieces of foam together:

I then added Great Stuff in the cracks and inside corners to fill in and help hold it together

(I always spray water on GS while it is curing to speed it up, hence the spray bottle)

More carving:

I am continuing the "stones" across seams and around corners to make it as seamless as possible, I might go back in with some air dry clay later to fill in small cracks before painting.

I'll keep updating as I make more progress

Love it so far! Great job - I am sure it will look super!

Wow - very ambitious for your first foam project but it's looking great! Also nice to see another BtVS fan around here.

Love what you've done. Will be watching to see how it turns out.

Don't forget that field stone is not necessarily all flat on the surface. So, sculpt the faces more. Make some more recessed. Especially at the corners, those need to be much more rounded out.

Thanks for the advice. I am trying to get as much texture as I can into the stones, trying to take advantage of the 6" depth I have. I will try to rough up the tops of the stones a bit more and hopefully I can add some depth with paint.

Also my theory is that the stone mason would choose the flattest side to go to the front of the wall lol
