I crocheted this using 100% cotton yarn suitable for spring and summer. Considering the characteristics of the yarn, I primarily used single crochet stitches. I took photos with a 650ml PET bottle and a 0.48L water bottle inside. The dimensions when laid flat are: Height x Width = approximately 17 x 10 cm Diameter of the base circle: approximately 7 cm Handle length: approximately 24 cm Hand washable.
