Sold as separates, our hob covers are thermally insulated to help keep the heat in, they also help to keep your Aga lids scratch free. Out gracious swooping Swallow decorates our Hob Covers on a pale blue background, as if it were flying in the clouds. To keep your hob covers as beautiful as they are functional, we recommend the following TLC every now and then¦ Machine wash your cover at 40 degrees. Re-shape it while wet & dry flat. If you really want to show some love, iron your hob cover while it's still slightly damp. As with all cotton products, the pattern will fade over time, but like well cared for, quality leather boots, we feel your hob cover will age well. To avoid premature aging, please DO NOT tumble dry!
