So my grandmother (who originally taught me to knit) told me that she knit continental. It wasn't until I'd been knitting for about two or three months that a friend of mine brought to my attention that she had no idea what I was doing, but it wasn't continental. For a long time I had no idea what I was doing differently, but I knew my stitches were turning out basically the same way (although now I see just a slight difference). I now realize that my grandmother (who I'm sure does not realize she's doing it to this day) knits, and consequently taught me to knit using combination knitting. Mine is even slightly different from what I've seen people doing when they use combination knitting- and it wasn't until recently that it became a little problematic for me.
My stitches still work the same, and I can do just as good work as anyone else, but I find that I have to find a way to adjust more complicated stitches sometimes, and it makes my pieces come out just a little bit differently. The difference is SO slight, but I see it sometimes. I tried to learn actual continental knitting, but it's so uncomfortable compared to what I'm used to, and I can't bring myself to try to break the habit.
Are there any other combination knitters out there? I'd love to hear about your experiences knitting and figuring out stitches, particularly pertaining to turning stitches.
