I've come up with a solution for loosing yourself. The Post Code Sock.
By in corporating the post codes of all your loved ones into your knitting pattern, not only do you no longer need to travel with your address book, but in the un likely event of something awful happening to you, someone else can post you to a place you'd rather be.
One sock says 'Please' across the top and the other says 'Return' - not 'Ret Ase' as it looks in the picture.
They are being knitted on 2mm pins with navy and cream 4 ply Wensleydale. I can't wait to finish them.
