Do we need to depict an animal great and or small?
No, but what ever you decide to enter must include an animal fabric. You may do an "I spy" landscape, vest or whatever, which under close inspection reveals an animal fabric.
You may celebrate our Challenge theme depicting a known species animal or your own imaginary animal which also includes an animal fabric.
Your entry may mimic our theme with a traditional animal named quilting block: Hen and Chicks, Cats and Mice or more abstractly: Turkey Tracks, Bear's Paw, or a border of Flying Geese, etc. as long as it includes an animal fabric.
Consider also how your entry will be displayed. It may need an accessory: a tea cozy needs a teapot, a doll may need a doll stand, a garment shows best on a hanger, etc. You will need to include these accessories when the challenges are collected for Challenge Night.
