I don't know if its because some of my fleece isn't very fluffy... but the liners i made are nearly trashed as i have nearly brushed a hole through them trying to get hay and hair off ! I have since bought some fluffy fleece but not using them until i get my new C&C cage... i have got some fleece which probably isn't going to be suitable for making liners as it is very flat if you know what i mean.. i will have to use that for something else !
