This is a simple pattern for a necktie. Half double crochets create a thick, stable fabric that is easy to tie but isn’t stiff.
This is a very flexible pattern, allowing for ties of different widths and lengths depending on the desire of the crocheter.
Gauge and hook size, too, are dependent on the crocheter. If you want a tighter crochet, use a smaller hook; for the opposite, use a larger one. I chose to use a G because the recipient of the tie wanted a tighter weave, but would have gone with an I if it were up to me.
You only need about one skein of worsted weight yarn for the average tie.
