Folded from a single piece of square Harmony paper. [15cm square] I coloured the centre part of the paper green for the clover. This model was created in 2002, adapted from Prof. Shuzo Fujimoto's "Crowding Butterflies".
Mari Michaelis has posted video instructions for Prof. Fujimoto's "Crowding Butterflies" here - www.spitenet.com/origami/Crowding-v.shtml
And the crease pattern here - www.spitenet.com/origami/pdf/CrowdingButterflies.pdf
You need to change some of the folds in order to simplify it for folding the "4-Leaf cLover".
