I have also become aware of the fact some fabrics stretch more one way than another - so that if I decide to "press" a block like I'm rolling out pie crust, sometimes I do get more stretching in one direction than another.
Yes, I do know that I am supposed to "press" - but I have had good results doing the rolling out the pie crust method. But - I am super finicky about cutting everything on grain and having no bias edges (when possible) on the perimeter of a block.
