I am happy to report that today I was able to find a B5638 along with a few others on my list. Joann's 99 cents sale on Butterick patterns ends Saturday.
When I opened the drawer to find B5177, lo & behold there was OOP B5180 staring right up at me. In my last post, the website says it's an OOP so maybe that was a recent update. But for right now I have enough new patterns to rotate and choose fabric etc. (and change my mind). LOL
