Haha it's not in my state, but it's only a couple of hours away so it's not horribly bad.
I know what you mean. My first bag ended up a lot bigger than I expected (and my liner expected >.> but I managed to squeeze the rim of it to fit since I didn't want to remake the liner). My second ended up a little wider than I thought it would, but it ended up being a decent size so I'm pretty happy with that.
Making your own patterns is hard, but it is very worth it when it works out!
