Help: made very cool, stitch dont know how I did it!

I was just learning to do seed stitch and did about 6 rows of 25 stitches (its just a scarf) that came out in a very cool cross-over pattern (almost like tiny cables).
I’m now doing a regular seed stitch (k1, p1) and I cant figure out what I was doing to get the previous very cool looking stitch.
I was doing knit one, purl one, but what was happening between rows? Digital camera not working or I’d post a pic. but any help you can offer much obliged.
Thanks!

Were you working the knit sts through the back loop? That twists the st.

Possibly! Thanks!
