A use for the Christmas tree after Christmas. A mat for just outside your door. Or maybe for paths. Excellent for keeping the mud and other barn gick out of your house. Also helps with traction on slippery days. Not just frugal, but free!
Monica from At Wits End Homestead is our how-to tour guide with this quick video. She points out that this is a Finnish custom - her husband is from Finland.
It doesn't have to be Christmas trees. It can be any conifer/pine/fir/spruce branches. Wipe your feet in the winter, and then the branches break down to feed the soil in spring.
