These are also a Christmas present which I must wrap so I can give belatedly tonigh.
They are for a friend's husband who's current favourite eye mask is really beyond its last legs. The elastic has lost its stretch and has been knotted so tight it gives him a headache while he sleeps. I feel my stroke of genius came when I sewed in the ribbon, so when this elastic looses it stretch it should be an easy operation to cut it out and add new.
If I'd thought about it while I was making them I would have photographed each step and posted a tutorial. It may happen yet, when I was trying it on last night to show DH he requested one for himself, so looks like there will be another in the making.
