I found the last UFO today when I was unpacking kitchen stuff ---
Have no earthly clue why I packed in that particular box
Stitch pattern How to Garter Stitch a Scarf on the Diagonal
found in the back of Scarf Styles
-- thanks to the help of a lovely LPL reference librarian -- aka Elbowgrease on Ravelry. We've been playing phone tag this week trying to figure out what book it was from & it wasn't until I unpacked my pattern books I found some actual scarf patterns we cross referenced with patterns on Ravelry.
