Not sure if this is the place to share this, but here goes......I went to our nearest city yesterday and visited my favourite store...Spotlight. I found knitting needles with a metric ruler printed on to each knitting pin. So when you're knitting your 20cm (8') squares you don't need to have a ruler or template handy..its on the needle!! I thought that was really cool (even though they were over twice the price of normal ones). Of course, last time I thought I'd made a fantastic discovery when I found short (kiddy size) needles and everyone already knew about them......so chances are you guys already know about these....lol.
Happy knitting/crocheting :))
