We started gluing corks that we had previously cut in half lengthwise to the wall. We started at the outer edge with full corks so that any cuts would be in the corner where they are least visible.
We tried to avoid having corks from the same type of wine close to each other. We also tried to use corks of similar diameters in each row so that they remained relatively straight.
It took us 3 days to glue up the 520 cork halves required to cover the space.It took 19 corks across the back and 7 corks on the side to complete a row. There are 20 rows of corks. Since the wall finish is light, any areas which would be exposed between corks (since they ae not perfectly rectangular) were colored black with a Sharpie.
