Coins are easier for me when I sew smaller sets, like sheets of paper, and only sew the column at the end. You can adjust the seam allowance to straighten out wiggles.
The quilting is basic straight lines with the walking foot across the surface.

The sky blues are soft and summery to me. More information on my blog. Also, Rachel posted another Chinese Coins quilt here a few years ago. And Wanda has a glorious version where the Coins/strings are vertical. And Brenda posted a scrappier one here.
