I am making "vines" so I dont really want holes or anything for crickets to get into. If you wanted to make larger diameter ones, you could make them look like hollow logs and allow your pets to go inside as well. This wasnt what I was going for this round.
Step 1: Set up your work area. **Definitely need some sort of mask as the PVC dust is crazy, and some eye protection, my normal glasses still allowed alot of crap to get in my eyes** .You need a bucket of water, a towel, your torch, lighter, dremel. PVC pipe of course. I also used a large screwdriver and a socket wrench extension and a old grill tongs to help me manipulate the hot PVC when I'm bending it. If you have a metal pipe that has a nice bend in it, you could have that handy as well, because you could slide it into the hot pvc pipe and make the bend identical and then slide it out when cooled, but only for a bend near the end, don’t get something stuck in the middle of your pvc pipe!!! I also had a soaked pair of gloves that I used when I needed to grab onto the warmer end.

Step 2: You could either bend first or dremel first, youll probably be doing both multiple times. In these pics I bent first, because you can see I am making a crazy shaped vine that will be going into a GS background. I dremeled afterwards. I don’t have a pic of my initial bending. But basically I got the picture in my mind of how I wanted it, then I heated up those areas where the bend would be, then using the socket extension, bent it in the desired shape. After I had all my bends, I began dremeling.

This is the messiest part and pretty much sucks. That PVC dust gets on everything. Here is a closer pic to show the texture I was achieving.

Then after you get done with that, u can torch again to make the white PVC brown. This is tricky. I found that a lower flame with smooth sweeping motions works the best, kind of like spray painting. I still don’t have this step done very well. Its really easy to have the torch heat up the PVC too fast and make a circle too dark.

But if you do make it too dark, you can always re-dremel. Basically it takes a lot of trial and error, and I'm still learning so this is where I'm at so far.
My first 2 logs.
