The importance of documentation

I believed I had it all covered: the needle size, the number of skeins, when to start binding off to get the perfect shape of the scarf. But did I? No. Barely no information of importance to rad in my Ravelry journal, more than size of needles and number of skeins. But did I use circular needles? And at what point did I start bidning off as it got all wind and messed up? Am I about to make the same mistake with this scarf? Cause I will knit another one, in a sort of raspberry cerise colour, but in Drops Kidsilk. See how it goes...
