good morning! i’m knitting my very first blanket & am stuck. I started with no “real” pattern. I knit 3 stitches on row 1. row 2 I knit one stitch, then did a yarn over, then knit 3, then yarn over then knit last stitch. I followed this pattern, by increasing on each end. Essentially, the blanket is a triangle right now. Now I need to decrease, but i want to make sure I still get the nice little yarn over holes along the edges. how do i do this? Thanks so much!

there is help just on this site!

look at the option at the very bottom:
yarn over decrease left slant / right slant.
The videos explain your new method, I guess.
I hope, this was enough to help you through. Enjoy your blanket.
