To get a "feeling" of snow, I use canned snow on the large glass panel in the kitchen door. I've had the same can of snow for about 10 years, using just a touch each year to get that wintry feeling.
For those neat, rounded corners, I cut a template from an empty cereal box, hold the template against the window loosely, then spray lightly on the glass corners of the panel. I've found that a lighter application of snow looks most realistic. One of my daughters says she loves, loves, loves the snow on the door.
Another 5-minute decorating project that I made this week went next to the side door that we use most and where packages are left by couriers. I cut boughs and branches of cedar, holly, and other evergreens and pop them into a pot of dirt. I added a bow and reused floral pick. I happened to be out adding "snow" to some pinecones, so I also gave a light dusting of "snow" to my greenery pot. Easy-peasy done.
As you can see, I like projects that give results quickly and without difficulty. These two projects met those objectives handily.
