I tie my scarf so "absent mindedly" by rote, that I had to break it down in parts.
I hope that it is easy to follow and truth be told practice makes perfect, so do your homework and no there will not be a test and you will not be graded on your results...self evaluation will be your measure of success.
I hope that these inages help to demonstrate the simple tie. This works with long scarves and generally the thinner ones. I have done this with a thick cashmere Club Monaco one and it is very cozy but quite warm as there is so much volume!
Drape scarf over your neck and let ends hang in front, grab the other side.
Wrap around your neck once loosely
Open up the loop so there is room to pull the other side through the opening
Place your hand through the loop and grab the scarf on the opposite side
Pull through the loop
and voila, the tie!
The internet has videos of scarf tying, YouTube for one.
I didn't spend much time looking up the tie I use because I do not know it's name!
Maybe someone does know what it is called...please leave a comment and or a link if you do know and we'll all be the wiser.
I know there are various styles of learners; audial, visual and experiencial so other than hearing me I hope that I have addressed the basics and those of you who wanted instructions are happy with the results.
