A few years ago, I found this pattern for a crocheted Hermione Granger face. I had a hell of a time with it; I kept miscounting stitches and getting tangled and so I put it away for awhile to keep me from setting it on fire.
I'm too stubborn to give up, so a week ago I picked it up again. I remember now why I wanted to set it on fire. But again, I'm too stubborn to give up (and if I don't finish it, then I don't know what to do with the little bobbins of yarn).
The pattern was written as "colour 2, 5 stitches," which was confusing because I had to remember which colour was which number. I fixed the pattern so it now reads "dark grey, 5 stitches."
Even so, any given line in the pattern reads like this:
Black sc7, Light Grey sc1, Black sc3, Dark Grey sc3, Black sc3, Dark Grey sc1, Black sc4, Light Grey sc1, Dark Grey sc2, Black sc3, Dark Grey sc4, Light Grey sc4, White sc1, Light Grey sc1, White sc11, Dark Grey sc1, Black sc3, Light Grey sc1, White sc1, Light Grey sc1, Black sc1, Dark Grey sc1, Light Grey sc1, Dark Grey sc1, Light Grey sc1, White sc6, Dark Grey sc1, Black sc7, Dark Grey sc4, Black sc2, Dark Grey sc4, Light Grey sc1, Dark Grey sc1, Red sc13
Now, even if you don't know how to read a crochet pattern, I think that you can still agree that this looks confusing and tedious and as though it would be easy to lose your place. You would be right. It's confusing enough that I messed up on the second row.
It's tangly too. I count 11 bobbins and a skein. You spend as much time keeping your bobbins in check as you do crocheting.
Literally a colour change every two stitches, unbelievable tangles, and it ended up being HUGE. And it clearly needs to be blocked (great).
Between Hermione and That Damn Bowl, I certainly know well enough to avoid any projects with 16000 colour changes.
