Can anyone suggest creative/cheap alternative to coping stones please..

for our garage?

My husband has sacrificed half of his beloved garage as we have a small garden. It's been bricked up in the inside halfway, and half of the front has been knocked through and the roof taken off that half to create a kind of seating area, as it's a sun trap.

So if you can imagine, it's like a garage with an attached C shaped bit you can sit in and enjoy the sun.

But at the moment, it looks like a garage which has fallen to pieces, lol!

We're having a friend come and render the inside to make it look a bit better as it's part breeze block, part brick and looks pretty scruffy inside. Where the roof has been taken off though, there is exposed brick at the very top of the walls which is pretty uneven and scruffy, and we don't know how best to finish it off - coping stones or something similar would be good, but they'd be quite expensive for us I guess.

A friend suggested flag stones cut in half, but I fancied something a little more creative, sort of a triangle shaped coping stone but as I think I may have invented this whilst daydreaming, I doubt we'll find them cheap in the shops!

Has anyone any ideas folks, please? Sorry if my description is a little vague. I will try and take some pics and link them up somehow to make it a bit clearer!

Thanks in advance for all suggestions/ideas!
