I don't mean your styles or anything like that, but what do your cut out patterns look like when you're done with them. I remember my mother mumbling over a pattern someone lent her once and telling me, quite crossly, not to wad my patterns up when I put them back in the envelope. Something I really didn't need to be told!
The top photo shows a wadded up, flattened pattern piece I found in a used pattern I was checking to see if it had all the pieces. I had to carefully pull it apart to open it. If I had been using it I would have had to iron it.
I normally fold my patterns as neat as I can get them. Sometimes I even go so far as to fold the pattern so the number is on top (I got the idea from someone else -- I can't remember who to give the credit to though). That tells you what kind of person I am.
Oh, and the wadded up piece at the top...notice the pattern by it has black ink and it has blue? Yeah, that piece didn't even belong in the envelope it was in!
