Vintage Patterns

I should probably state right off the bat I am new to knitting but I have found a vintage pattern that is simply beautiful and looks fairly simple. I think I have figured out most of the different terms used in the 50s compared to what is in a standard pattern now (I hope), but one of the lines says the following “K 6 sts picking up back loop of each st”. What is it saying when it says to pick up the back loop. Am I just knitting the 6 stitches or am I doing something different with them?

Sounds like you’re supposed to knit those 6 sts through the back loop.

Anyone else out there want to wade in?

Never mind I think I’ve got it.

I think you are right. I just found a description and that is what it sounds like to me too.
