Really I just think it would look better with a pattern fleece paired with a solid fleece on the botton. And that way the uhaul pad would be covered. The uhaul pad isn't really that pleasant to look at
.
I heard some people complain about using 2 uhauls with 2 fleece and it not drying well. I don't have a washer or dryer so I have to go to a laundry mat to wash my stuff. I was just gonna make a liner with 1 uhaul pad sandwiched between 2 fleece. But like I said I don't want any pee going through the second fleece and onto the coroplast. So really if I did a waterproof layer then the second fleece would just be for looks.
