I made a pie.
Step 1: The bottom half
Set one aside, and flatten the other one out and put it in the bottom of your pie dish.
Step 2: Strawberry!
Step 3: The top!
First, take the dough you set aside earlier and form it into a ball. Then flatten it into a a circle about the same size as your pie dish. It shouldn't be thick.
Take a knife and divide the dough into long strips about an inch to half an inch wide. I reccommend thinner strips, but it's harder to pull off this "lattice" effect when they're thinner.
Step 4: The hard part
Now fold every other strip back about an inch.
Lay another strip on the dough, then fold every other end over. The pictures help a lot.
