Quick Disconnect for Christmas Track

Have you tried using plastic tie wraps? Put one around the cross-tie and through the plywood. You can buy them at Home Depot in bundles of 500. All you need then is a drill and a diagonal cutting pliers. Don't use a pair of scissors with the tie wraps as it may break your scissors, tin snips will work good too.

If too much green showed through try using a cotton roll from a craft store and sprinkle some sparkle material on the cotton, don't have to be that sparkle stuff, the sparkle is to make it glitter like real snow will when the sun hits it. Then use hair spray to hold the sparkle stuff in place, I used a pump spray type of hair spray and not an a can of hair spray.

I used the cotton and sparkle stuff on an H.O. race car track and it worked well. Just keep the hair spray off the track or wipe it off soon after spraying if it gets on the track.

Not what you're looking for, but have you ever thought of covering the other side with white & attaching lionel tube track? You would have < $50 into it, and you just use the side of the board that is correct for the holiday, with removing track constantly.
