Wallflowers (Plastic bag hanging flowers)

Step 3 Crease and Cut

Fold bag and cut freestyle a traditional petal shape along crease. Cutting on crease creates a symmetric shape.
Try different sizes and shapes. From big fat teardrop styles to slender petals.
Also, pay attention to the pattern/text on the part of the bag you are cutting out to create interesting flower designs.
This petal will serve as the pattern for the remaining 4 petals of one flower.
