Portions of the Irish chain are complete.

The construction seems slow.
In the past I just plowed ahead sewing two squares together then pairing those and so on. The result was seams that did not fit together — a mess!
So this time I have attempted to be more methodical. I create one quarter, pressed in to make sense, repeat that for each quadrant, then place it on the design wall seams on top. This way I can see them for pressing the adjacent blocks.
This was all fine until last night I realized I had sewn a 12 patch backwards. The whole thing, every seam on the wrong side.
All complete and corrected. Lets try and NOT have that happen again!

You can see here the green square to the right of the diagonal row. Looks the same in the photo — looks similar in person!
