just curious if you had tried anything and how it worked out.
I've done self bondage a few times and i found an easy way to tie my hands behind my back was by taking a bandana (or in your case a scarf)
and tie the ends together so it makes a circle. Now put both hands in and twist is till is tightens and restrains.
I've read some stories where people handcuf themselves and put the key on an alarm clock so when it goes off it shakes and drops the key to the floor.
So they are able to sufficiently tie themselves up and remain tied until they choose. Although test the alarm clock out before trying it, safety is always important.
I wish you good luck and feel free to drop me a line and let me know how it went
