Cast on Help

How is it best to gauge how long the yarn is when doing a long tail cast on? Is it that you wrap the yarn around the needle as many times as there are stitches or is it one and a half times? I can never remember!! Any info would be appreciated

I wrap the yarn around 10 times and I always leave about a 8 inch tail so if I need a few more I’ve got them. It doesn’t always work out, but it works pretty well and after a while you can gauge better what you need, too. :thumbsup:
