3 With your hand that’s now free, pick up one of the remaining two corners that’s hanging down. Bring it up to meet the two corners of the fitted sheet that you’ve tucked together, and tuck it over the top of them.
4 Reach down to pick up the one remaining corner, and tuck that over the top of the other three corners.
5 Lie the fitted sheet on a flat surface and straighten it into the most regular, rectangular shape you can, keeping the corners tucked together. Fold the two edges that show elastic inwards, then fold the sheet in half over the top of them to hide the elastic. Fold in half again if needed, until the fitted sheet is the shape and size you want.
6 Congratulations – you’ve folded your fitted sheet! For a linen cupboard to put all others to shame, try tying the fitted sheet together with the rest of the bed linen that makes up your set, using ribbon or offcuts of your favourite fabric.
