We Danes love crafting in case you haven't noticed. So of course DIY christmas ornaments are a must.
The 'Cut-and-glue' day is mostly a primary and middle school thing. On this day there are no lessons. Instead every classroom receives a large supply of colored paper, glue and scissors and all the kids show up wearing santa-hats.
While the teachers hand out christmas cookies everybody's braiding hearts, folding stars and making paper garlands, competing to make the longest one. One time my class made a paper garland long enough to reach around our building.
