What Does Psalm 23:3 Mean? Recycled Wool Tartan Hot Water Bottle Covers Traditional. If you love your GGCo. Recycled Wool Tartan Blanket and have been dreaming of a matching tartan hot water bottle cover, then your prayers have been answered! Handmade with love in Victoria by clever Therese from Chooktopia, these recycled wool tartan hot water bottle covers are just the thing to get you through those chilly nights in style! Thoughtfully designed with our love of adventure always in mind weve left the tassels in place on our new hot water bottles covers which fold open easily for you to pop in your own 2L hot water bottle (but if you need to buy one we recommend McGloins 2L Hot Water Bottles sold at most Australian pharmacies because they meet Australian Safety Standards). Add one of our Aromatic Candles to create the perfect Australian made gift that says cosy up and stay warm in practical luxury as is our trademark! Details Made from our recycled wool blankets comprised of 75% wool and 25% mixed fibres which include synthetics to allow for ease of care. Care Instructions Handwash in lukewarm water with wool specific detergent. Lay flat to dry.
