Tunisian crochet

[Chars]

I am doing tunisian stitch it says knit 85 and do 13 in black and knit82 that worked out right the second row says knit78 knit13 in black in this part it seems to have 4 stitches to many can. Any one help

Totally have never done colorwork in Tunisian, or much Tunisian beyond entrelac in TSS, hopefully someone else will come along.

But just doing the math, 85 + 13 + 82 = 180     

And 78 + 13 has got to be missing something.  It would work out if the third number were 89, or other color changes that added up to that number.

Is this a free pattern on the net, or could you give us the name of the pattern and the source (book, Etsy shop, whatever) so we can see if not the pattern, at least what the finished item looks like?
