Garnish with cinnamon
A few years ago, when we had the nice old gazebo, we decorated it nicely so that it was ready for cozy moments with guests. We decorated with cinnamon, baked sweets with cinnamon, and made decorations with cinnamon sticks. You can find the recipe for a lovely cinnamon cake here or get nice ideas for decorating with cinnamon sticks here.
A fine fir tree, a rustic dining table and chairs and plenty of lovely furs and warm blankets are almost all that is needed to create a cozy corner. Also remember light chains and possibly candles to complete the coziness.
