I have discovered it works great as stuffing when I'm sewing bowl fillers like these hearts.........
I was stuffing some more of these last night, and used "real" stuffing. I actually like the Buffalo Snow better!
I don't have the original bags anymore, so I can't tell you anything more than it was called Buffalo Snow. It came in bags about the size of a bed pillow. I had bought it at Goodwill before Christmas. It had originally come from Walmart.
I would assume it's only in the stores at holiday time. But maybe there's still some out there in the clearance sections. I wish now I had bought more of it! It's long gone now, but I'll be keeping an eye out for more.
