Thank you so much, to whoever it was that mentioned how to properly press our blocks, a couple of weeks ago. I tried to find the post, but couldn't.
They mentioned to finger press the seam over to the one side then just press the iron down on it to set it.
I know this sounds stupid but I didn't really know how to press things. Now that I do it correctly there is a huge difference in my 1/4" seams. I was mangling all my seams with the iron after I sewed them.
It just goes to show that no tip is to small to be shared.
