If you do not have time or disposition to do this, simply wind in the line with the tangle right into your spindle and attempt to unravel it in your home or when you have time. Otherwise you will be inclined to take the course of least resistance, which is to massacre the tangle to your irritation later.
Do not tighten up the tangle. While to a lot more conveniently see the loops you might need to draw on lines, thereby tightening up the tangle somewhat, avoid attracting them completely tight. Doing so will make it much more tough to draw out the loops, and will give you kinked portions of the line as well. As you understand, kinks in the line lower its sensitivity to attacks and increase the line's propensity to form brand-new tangles.
