If you do not have time or inclination to do this, simply wind in the line with the tangle right into your spool and attempt to decipher it in your home or when you have time. Otherwise you will certainly be inclined to take the path of least resistance, and that is to massacre the tangle to your irritation later.
Tangles happen when loops of line are caught by other loops. Such loops are frequently just like slip knots, during that the knot disappears when the trapped lines are pulled out. The trick, for that reason, is to check if a loophole is a caught one, figured out via parallel lines going under a single line, and taking out the trapped loophole so the trapping lines can unwind entirely. Draw on a loophole as well as view where its continuation is, after that pull out the proceeding line to remove the caught loophole.
