Sawing a piece pallet lengthwise through.

Then sawed right and left sides.

Drag it off.

Coat it in the color that you want.

Next, a wire attached with two screws on the back.

Then you take two boards,

and label each on both sides with what you want to make. I have it with spring, summer, autumn and winter labeled. For Christmas, Easter, etc. then you need correspondingly more boards. They are attached with a screw, then you can change the boards as needed quickly.

Here is the end result. The decoration consists of real natural flowers and leaves. For another year, then you take something corresponding thereto. How I decorate it to the other seasons, I will also like to show here. If all seasons were once decorated, there is finally a collage where you can view all seasons times together.
If any of you wish to imitate it, I hope you enjoy it.
