I raided the stash for a zip, and begrudgingly settled for a white zip. I don't have a pale blue thread, which I find hard to believe. I have a memory of being so excited when this fabric arrived that I raided the stash for thread + zip. I know that I had them, but they weren't with this fabric. Mind you I hadn't put them all in a ziplock bag together so it serves me right. I have another "current season sewing" box to look in before I buy thread.
When it came to buttons I looked first in the gift bag labelled 1940-1965.
Thank goodness there's enough of this navy ridged button, plus it's the right size. The ridges are reminiscent of the lines in the background and ship so it's a clear winner.
