Stay cozy with the Cosmos Hot Water Bottle Cover Crochet Pattern – a retro-meets-modern design featuring an 8-petal flower granny square and easy envelope construction.

This stash-busting project is perfect for using up yarn scraps and experimenting with colour combinations.

The step-by-step PDF includes clear written instructions (US terms) to fit a 2-litre hot water bottle, helpful photos for each stage, and guidance for assembly.

Crochet your own floral hot water bottle cover or make it as a thoughtful handmade gift to bring warmth and comfort.
