I cut the remaining squares and was able to complete the whole design. This is what it turned out into:
There is only one major problem, the qr code cannot be read. And at the moment I do not know why this is. My first pinning showed some gaps in between the squares, so I repinned it. The picture is taken after the second pinning. Are the pins the problem? Are there still to many gaps? Not enough contrast between the background and the squares? Not square enough? Right now, I have no clue what the reason is. If you have any idea why this is, I would love to hear it.

And something else. I am participating in Beat the Winter Blues blog-hop party - see this link: http://quiltinggallery.com/quilters-fun/quilters-blog-hop-party/. Coming Friday I will post what my give away will be.
