Felted slippers

There is this old newspaper cutting I always kept : a pattern to make slippers from knitted squares. It reminds me of the slippers my grandmother once made me. And so it's my turn to make these. I used wash+filz-it by Schachenmayr. After the knitting and the sewing, I put the slippers in the washing machine and they felted nicely into these cosy friends for my feet : another happy thing!
I found a similar pattern in 'Knitted & crocheted slippers', by Alison Howard, p.14.
