I was looking through pictures on my computer and and I was like “Why are these random pieces of fabric here?” Than I realized I was supposed to show you guys how I made them. I got all my fleece on sale so I have no clue how much this would cost. :/
So, it’s made up of three (sort of 4, actually) layers.
The bottom layer (white fabric) is usually used as a crib liner for babies. It’s got rubber in the middle (although you could never tell) which makes it waterproof. The actual material just feels like really stiff cotton. The middle layer (yellow) is pretty much a towel. I got it at the fabric store so I could use one big piece instead of a lot of little towels. The top layer is fleece. I’ve doubled it up so it’s extra soft for my piggies. Originally I sewed all the layers together. It was SO heavy though. It was even worse when I had to take it wet from the washing machine to the dryer. So Now I just lay them one on top of the other. I just tuck the fleece over the other fabrics so the piggies don’t get under them. Cutting them to the shape of my cage wasn’t hard either. Oh, you’d have to put foam mats or coroplast under them. This isn’t enough to hold up your piggies or protect their little feet from the bars of the cage.
Uhm. I guess that’s it. Yay!
Here’s a picture of their cage. (My little sister took it yesterday.)

Right now I’m using foam mats. I’m getting my coroplast Wednesday. I’m so excited! :D
