Easy way to get a pdf for down load...

You can move just a COPY of the thread that has the sew along in it to the in box.
once there you need to delete responses (unless they are Q&A then they maybe helpful!) and make sure the title accurately describes it etc... clean it up if needed.
then under Article Tools click "show printable version" then you can just do file> print> pdf and it'll save the printable version whic already has the sewing mama url etc... in it and you don't have to worry about downloading/copying etc. It's much quicker!
