Stuck on pattern joining

[pehonnen]

I'm really stuck on the afghan we are doing. It's on the Border Joining Row. I'm attaching instructions on border, a finished pic from book, and the end of the border I've completed.

What you are doing is 'joining as you go'.  Your instructions are a little unclear, but what I'm guessing is "slst in base of last dc on row 1" refers to the last dc of row 1 of the blanket, not the edging square; then "dc in last dc on working row" - working row meaning the edging square you are finishing the last round of.

There are many ways to JAYG, but the simplest is like this one; working on the last round of a motif, you 'reach over' to the other thing you are joining, stitch into the 'other thing', then come back to the motif whose last rows you are working to finish.

Thank you, Granny Square. That makes sense to me and I will do that. Appreciate your help immensely!
