I don't use pinking shears. I find it makes it too difficult to get that "perfect" 1/4" seam. I never know whether to use the inside or the outside of the "pinked" line as the edge of the fabric.
As for jellyrolls and turnovers that come cut with pinking shears, I find them hard to work with for the same reason, and I don't like all the lint that they create. I have to take the loose pieces outside for a good shake before I start using them.
IMHO
