I learned how to do this at a Tupperware party in the 70's and I have made pie crust this way ever since. All you need is a big plastic bowl with a good lid. Of course it was a Tupperware party so you were supposed to buy that bowl, which I did but it finally bit the dust.
You will be amazed at how easy and fast this makes putting your crust together.
Find your big plastic bowl with the lid. Go ahead, I will wait.
Put the flour, sugar, and shortening in the bowl. (Sugar is for the dessert crust or use salt for savory crust) Put the lid on and shake it until small pea sized balls are formed. Take the lid off. Now add the water but start with four or five tablespoons at first. Put the lid on and roll it sideways. I think this is good exercise too. You don't feel so bad about eating the pie when it is done. You can make big circles in front of you for the upper arms. Open the lid to see if it has formed a ball. If not add some more water but just a little at a time.
Now it is time to roll it out. It is very flakey because you did not touch it while making it and the food processor did not beat it up.
