And then the pattern on each side on the zipper really come together. Sometimes it is difficult to get it right. I am not a pro.
And here is a picture of just the pattern and the zipper:
My next project, which I already started is a lettlopi sweater for my boyfriend. I made my own pattern and started to knit. The ground-color is black. It will be interesting to see the result. To see how the colors will match up together.
