Help Finding this Yarn (Or Similar)

[kmaclean]

I like this yarn: http://www.straw.com/cpy/yarns/bamboozle_card.html

but I haven't been able to find it in my area (if there's anyone from Ontario that knows of a place that carries it, let me know!). Has anyone seen it for purchase online somewhere? Or do you know of any similar type of yarn that I might be able to substitute? The webpage doesn't seem to specify the weight of the yarn, so I'm not sure what to substitute .... If anyone has used this yarn in the past and can offer some insights, it would be much appreciated!

Thanks!
