Given the wife's ever changing thoughts/moods/whims on Christmas tree locations, I've simply been using four pieces of white felt for the snow on my holiday layout. This year, I've about lost my patience with that set up. I've tried taping them together, thick overlapping, and using a white felt or fluffy snow sub base but, not matter what, the slightest movement always seems to somehow pull them apart and reveal a crease or the floor somewhere. Plus, it's a pain to keep clean.  

Building an actual holiday layout isn't an option since the tree location and space available may change from year to year. I've gotten to the point that I'm seriously considering ordering a piece of white boat carpet and calling it good (and I can always put furniture on top of it if it winds up in a tight spot).  So my question to the Forum is, what do you use for snow on your holiday layout?

Thanks
