If you use or used to use Morning Glory polyfil and can no longer find it, well head off to your local Christmas Tree Shop.
They have 1 lb. bags of Buffalo Snow, it's pretty much the same as MG. It is now on clearance for $1.34 per bag!!!
I got 25 bags, could have gotten more but I use the "other stuff" and supplement with the MG or Buff. snow, and I have several 5 lb. boxes of that.
Now, where to put it all............................?
