I have been sewing strips around charm pack blocks (2.5 strips around 5" precuts) and some of them seem just a bit off - they seem to be pulling to the right as I sew.
I sew at my dining room table while sitting on a wooden stool. Works for me for now anyway. Finally figured out I wasn't lined up straight with my machine so the usual guides I use to get that 1/4" seam were just off a bit. Once I sat straight with the machine the problem stopped.
Make sense to anyone else? As I got to the end of each block I was pulling it just a tiny bit towards me and ... I was off.
Perhaps I just started paying more attention, but whatever the reason it seems to be fixed.
