I couldn’t resist posting this paper poinsettia (though it is surely too difficult for kids to make). I borrowed the idea from HERE and as I had no such two-colored paper, I glued some glitter on the folded lines.
You need two colored A4 sheets. Fold each one lengthwise. Cut 2 squares from each strip. You need 5 squares for each flower.
Glue all 5 petals together. This turned out to be the most difficult part :).
