I have a tarp on the carpet, puppy pad layer, standard blanket that all stays put then puppy pads and kids fleece blanket on top which gets changed and washed . I also put pieces of fleece in high use areas and refresh them daily when wet etc and find that easier to manage and keeps them clean and dry and me sane. Warning though your washer can become full if hair and hay washing the fleeces. I find the kids fleece blankets lovely and soft but thin enough to dry quickly too. Hope that helps x
Mine are in my lounge in run on floor btw , no drafts tho
