Measure and cut card stock templates for the main pieces in three sizes. The templates I used were: Large= 6.5 inches/16cm, Medium= 5 inches/12.5 cm, Small=2.5 inches/6.5 cm. Templates will be used as a rough guide. You are aiming for slightly irregular shapes.
Cut 6 large shapes, 12 medium shapes and 24 small shapes.
Use a circle cutter or make templates and trace and cut for the center circles. Large centers=2.5 inches/6 cm. Medium centers=1.75 inches/4.5 cm. Small centers=1 inch/2.25 cm.
Create centers by slitting paper almost to the center to divide circle in roughly 4 quadrants.
Pinch each quadrant in the center.
With the center right side up, pinch
and fold in while pushing down to create a flat bottomed center with 4 "petals".
Glue centers to each flower.
Use adhesive gum (the reusable gum used to hang posters) to attach the flowers to the wall. Start with the large shapes and work down to the small ones. The adhesive gum will allow you to keep rearranging until you are pleased with the composition.
