Either way, a razor blade wouldn't touch it, & a dremel even struggled to get through it. I didn't cut mine in a straight line though. I followed the stump & cut between it & the rock/mud wall hopng to blend the seem better.
JK47 mentioned that same thing about his other backgrounds... he sanded his 300 gallon background down and some areas were like concrete. That's a good idea about cutting around the stump, maybe I would do that if I were to do it again. Looks good so far and I'm pretty sure when I get some algae growth that you won't be able to see anything at all seam wise.
