I bought a flexible plastic ruler to put in my knitting project bag. I'm really pleased with this ruler. It's hot pink, my favourite colour. The shape and texture also delight me because they remind me of a candy we used to buy as kids at park concession stands and corner stores. The candy was a wide strip in Neapolitan flavours. Can't remember what the name was.
I have a couple of perfectly good wooden rulers, one I kept from elementary school complete with childish doodles and one clever one inscribed with a list of the rulers of England but I bought the flexible ruler thinking that I wouldn't want a wooden ruler to break in my bag. However, this begs the question, what exactly do I think my wooden knitting needles might do?
