Confetti is simply part of the carnival! Make large confetti out of no longer needed or already collected screw glass lids. Also, the lids of tin cans (only when a can opener is used to round off the edges!) are wonderfully suitable to glue them and hang them on a cord.
A room decoration, in which the smallest ones can already co-build. The sticking on of the colorful snippets playfully promotes the fine motor skills and the concept of sustainability in the use of materials, which are actually to be thrown away, is already conveyed to the smallest ones.
See for yourself how easy sustainable crafting is!
