I've always used WOF and the last quilt I used LOF.
For first time out, I'm not happy with the results of the LOF, and think I would have had a nicer finish with the stretch that comes with WOF.
I'll be looking to see what others have to say ... so please keep in mind that my LOF is a one time only experience. (And yes, there may be other factors that play into it, though the borders were flat as a pancake before I started.)
