Hello and happy day of collecting,
Today the Wichtel family goes out to collect pine cones, which also sounds like a nice family activity for you.
You need wool threads, gift ribbon or other threads for decoration for the thread crafting. You can first use the stars as a template to make even more stars. The star in the middle (sample image) is only an option if you cannot collect fir cones. If you find a small cone, he can replace the star.
Have fun collecting and tinkering.
