Help identifying my pattern

Picked up my knitting again after 3 yrs, would love to finish an afghan that I started but cannot seem to determine exactly what I have already done. I have a simple k6 p6 on my needles, but I have attempted to do samples of knitting the knits and purling the purls, I am not able to yield the same results as my afghan. The stitching looks the same on both sides…help please!! Might be reversed stockinette, except I can distinguish the knits and purls on the needles. I have pictures if I can figure out how to post. Thanks, confused catie
