Pattern Help!

[Jayhawker13]

Hello! My grandmother recently passed away and in her belongings we found a partially crocheted blanket that she started for me but wasn’t able to complete. I’m unfamiliar with the pattern and was hoping someone might be able to help me so I can finish the blanket. 
 

thank you!

Welcome to the 'ville, and my condolences on the recent loss of your grandmother.

I think your bottom 2 photos are upside down from the direction the piece was worked, and the top one is I think sideways. (edited to add - not criticizing, just wanting to help you see what's going on with the stitches).

I believe this is c2c or 'corner to corner' stitch, it's also called crazy stitch.  You can make it in rows, and what I'd guess you would call rounds (starting from 1 corner and working corner out increasing each end to make a triangle, then decreasing at some point to turn it into a rectangle).  (confession, I don't make many blankets and have made a couple of swatches but not used it in a project).

My bad, I thought they were the same thing. 

I rarely make blankets and have never used it in a project, I think I first encountered it at a crochet.about.com (that became the Spruce Crafts) before I'd ever heard of c2c.  This wasn't the article I recall, but apparently I'm not the only one who mixes the stitches up!  (sorry for the confusion Jayhawker13)
