Ok, I did some math on what I could find and here's what I got. I tried to get pretty close, but most of these numbers are pretty round.
Cabled Mug Cozy- 50 yards
Jimmy's Hat- 200 yards
Jimmy's Matching Scarf- 340 yards
Casey's Man Hat- 220 yards
Sweater Bag- 765 yards
Fetchings- 82 yards
Thats a total of 1657 yards. That is .94 miles.
Though that is a pretty sad list of FOs. Lets fix that....
