QR Code with Colored Pattern

QR cross stitches are so fun and easy to make because they're super portable. This is my second attempt of trying to incorporate color into a QR code.

Every QR code has those three distinctive 7x7 squares in the upper, and lower left corners. In the larger ones, there is a smaller square in the lower right quadrant. I decided to highlight those squares and do a large plus-sign design in the middle.

Does it scan? Mostly. Up close it's not the best, but it consistently works from a small distance. I'm thinking if the colors matched more in value, it might work better. The patch on my backpack, which is about the same size, works fine when I scan from up close.

In terms of patten, I think this one is much more successful than my previous attempt. It's difficult to make a pattern stand out because of the random-ness of the code... Color blocking seems to work well, especially when the pattern is obvious. Even this plus looks a little off-kilter on the top because there just to happened to be hardly any pixels in the left most column. I picked the design arbitrarily ("I'll do a seven pixels thick plus-sign because that's the width of the squares!") but in the future it might work better to adjust the design to fit the code.
