Even though clothing was suggested as a filler, I found using 2 regular pillows made a much less lumpy and cosy filler
I love these things! They have saved me time, money, and mess
All dog inserts deteriorate quick and when taking the cover off to wash, the cedar chip and stuffing fall out everywhere
I've used it with cedar chips for an outside bed for a while, and have since filled it with leftover stuffing from a smaller bed my dog tore apart and some new stuff
I have the duvets also for inside and the outdoor cover of the patio
Now I can put all of the stuffing into the stuff sack and put it inside the dog bed cover
