My daughter made this yesterday at our preschool co-op. It’s a Liturgical Season Wheel. This was a craft for the 3-4 year olds, so they only covered liturgical seasons (not liturgical days or all the colors). You could certainly modify the concept for older children to include more colors etc.
This is the main piece you have to make. The lines were lightly marked with a pencil ahead of time for the kids, and the pieces were already cut. The pictures came from Catholic catalogs. You can click on this picture to enlarge it. The season is written opposite the picture because of the way the window is cut in the top piece.
This is the top piece. It needs to be the same size as the bottom one, and the windows should already be cut for small children. Then you make holes in the middle of both and attach it together with a brad.
Here is the finished product after you attach the top window. You can turn it and just see one season at a time! I’m very excited to hang this up and let my daughter keep it turned to the correct season!
