Knit yourself a rainbow hands-free reusable water bottle or drinks carrier, with your choice of short wrist strap (with optional clip) or extra long strap to wear across your body or over one shoulder.

These bottle slings are an easy knit and completely seamless. You will only have two ends to sew in: the cast-on one and the cast-off one.

The bottle sling will stretch enough to fit a wide variety of shapes and sizes of bottles and cups, up to a full wine bottle size (75cl / 25 fl oz), but folds up very small when not in use.

Make one for each of the kids in different colours so they know whose water is whose (and can carry it themselves!) - great as a stocking filler or back to school gift.

ECO-CREDENTIALS: helps encourage use of reusable water bottles, coffee cups etc. and if it’s made from 100% natural plant fibre it will eventually biodegrade (but not until it’s been used for many, many years!)
