I was purposely unspecific in this case. The pattern that made me ask is a quilted project.
Never before released into the wild, which means it wouldn't be in the library or sewing books, etc.
I do the same. I hit the thrift shops specifically for machines and quilting books. For a while there, we were hitting thrift shops any time we were out while I was trying to collect the whole Singer Sewing Reference Library. DH finally bought me the last few used off Amazon because he figured that was cheaper than the fuel we were spending.
