I'm constantly buying more pattern books, magazines, leaflets, etc. Right now I have 316 in my Ravelry library: 91 books, 164 magazines, 57 booklets, and 4 PDF files. I also have several other books and magazines and booklets that are not found in Ravelry. If I ever use any of those patterns, I will ask Ravelry to add them to their database.
I also have 240 issues of the old Workbasket magazines. Right now, they only have about 15 issues in the Ravelry database.
This doesn't include the hundreds of free and purchased patterns I have downloaded on my computer.
I'm a confirmed pattern addict.
