Each of the three clovers in the picture was made out of two squares of paper of the same size: One for the leaves and one for the stem. No glue was required to join the two pieces.
You can find the diagram here. Although the diagram was drawn with two color paper for clarity purposes, I like to fold the model with paper that is the same color on both sides.
For the big clover, I used two 6" (150 mm) squares of tant paper. For each of the smaller ones, I used two 4" (100 mm) squares of kami paper.
I hope they bring good luck!
