In part 3 I made some little changes. I wanted the colour change you see when you work garterstitch, to appear on the backside of the shawl. Therefore I purled some stitched instead of knitting them, when colour 2 was introduced:

row 2: k3, yo, p20 …
row 4: k3, yo, k24, p3 …
row 6: k3, yo, k31, p3 …

When I reached the w&t-stitches I picked up the wrap in part 3 because I liked the look together with the following stitches that I purled.

At the beginning of part 4 my stitch count was not correct. Somewhere in the prevoius parts I must have made an mistake. I had only 345 stitches on my needle and not 346 as was mentioned in the pattern.

I still had the markers on my needle from part 1.
In the middle Part I had no changes (still 30 stitches between the 2 markers), on one side I hat 156 stitches and on the other side 159 stitches. Maybe I made a mistake in one of the short row parts 2 or 3.

I cheated and made an extra stitch on the side where I only hat 156 stitches and continued with part 4.
