Maybe this is a silly question, but is there a good way to get parchment
paper (off a roll) to lie flat? I have to bake a lot of cookies, and I
like to line my pans with parchment paper. But the parchment paper
continually rolls up at the edges, and means I have to push down the
paper constantly when I'm trying to drop my cookies. It's minor, but
it's annoying.

And is there a brand of parchment paper that comes off the roll more
easily? The only kind readily available here is by Reynolds, and the
roll is a pain to deal with - every time you pull on the edge, the whole
roll pulls out of the package. I'd be willing to search for or order a
different brand if it was easier to work with.

I considered buying pre-cut sheets, but they're the wrong size for my
pans (they're for half sheet pans, which won't fit in my oven). It
seems foolish to buy pre-cut sheets and then have to cut them down to
fit my pans.
