Mike you need to get those adhesive backed felt from Bunning's or Mitre 10. They used to have some pretty good stuff but lately I have not been able to find them (maybe someone else might know where to find these). I got some Protostar flock paper from the states and they are a shocker. They don't stick down very well when overlapped so my flock is quite messy as well. But I like to think of the wrinkles as offering additional baffling
