Guinea Pig cage fleece lining question?

You need to go to a Fabric Store like Hans or Joanns. You can find Fleece online, as they have websites(Well i know Hans does). Walmart sells fleece too, but it is in the fabric section. i don't know if your Walmart has one. Call and ask. Look into getting a sewing machine and finding one that is easy to understand. It will do the sewing!
