Today's blog is brought to you by the letter 'Y'purple button knot and diamond sinnet letter Y One of the many names for the Chinese button knot is the one strand diamond knot. Strangely enough, the exact same knot can also be called the two strand diamond knot. This wackiness is due to the idea that if the top of the knot is a loop, then there is only one strand of cord tying the knot. If, instead, there are two separate cords instead of a loop at the top, then it is a knot tied in 2 cords, hence two strand button knot. It's a very fine distinction that I chose not to make most of the time (what exactly is it if you've tied it with one "strand" and then cut the top loop, eh? 8)
