I think it's worthwhile to try at least once! I've been getting ready to do a mock trial setup outside my home with my table and popup and all my holders, seeing what I'm missing or what would work better, how best to set up and signage, etc. If you've got all the things you've need and it won't put you out more time and energy than it's worth, I think you totally should!
Do you still make your cat ear beanie the same way you make them in your tutorial? I just made a black and green cat ear beanie using your pattern a couple days ago, and something about it looked a little different than yours (I followed that pattern to a T, so I am 99.9% sure it wasn't a missed row or stitch)
