All dyeing is done by hand in small batches (about a set of queen-sized items, i.e. duvet cover, fitted sheet & 2 pillowcases), so dye lots will vary slightly. If you order several items in the same colour, we will make every effort to dye as many of them together as possible, however, it is possible you may receive items from slightly different dye lots. The typical variation in colour that may occur is shown in an image on each product page. Every computer monitor will display colours somewhat differently, so use our colour images as guidelines – the actual colour may not be exactly as displayed by your computer. For an explanation about why colours sometimes look different online and in person, check out our about colour page. Following our washing instructions will keep colours true for a long time, while the cotton will get softer and softer, a lot like your favourite, old jeans. Just like everything at bed, these sheets are all sold individually so you can mix and match colours. Please note, if you want 2 pillowcases in the same colour, be sure to order 2, because they don’t automatically come in pairs.
