Bring an item from home that inspires you. It could be colourful patterned scarf or fabric or some other object, natural or artificial.
The possibilities are endless. Interpret in your medium of choice.
Incorporate fabrics and objects or floral and fruit with a backdrop of a patterned fabric.
Patterns do not have to be flat, patterns can have rhythm. Explore how patterns can be fluid and change shape as fabric folds and recede from the viewer.
OR focus just on designing a pattern from one item eg. a leaf
OR explore the pattern on a pineapple or a many petalled flower.
