ACADEMIC BOARD
Then there was also a doll's ice board. Colored thin cardboard, marker and contact paper. How to do it: Create a template first:
1. Fold an A4 sheet twice.
2. Draw half the sled board and cut out. (Then it will be symmetrical.)
Then you make the sled itself:
3. Place the template on colored cardboard.
4. Draw around and cut out.
5. If necessary, draw on details.
Good luck!
