I replace the one pin with 2 pins at the proper direction for sewing.
When the fabric is in the machine I fold back the freezer paper so I can see the pressing mark clearly. I sew along that line.
When I am done I check it again to make sure the seams are still lined up. They are and I am happy and ready to move on.
Now I add the next block and once again I am not happy. I am off about 1/8 of an inch with the point of the bottom left block.
I decide I must pick out the entire block to replace it where it should go.
