Ack! My Cables are wonky!

Hi there, attempting my first cabled project. A blanket.

It is three stitch cable, holding cable needle in back. My cables do not look like the pretty ones on the pattern. What am I doing wrong???

I watch to make sure stitches don’t twist and I make sure I’m knitting not purling…help!!

The purl sts should be in their column and the knit sts are the ones that should be crossing over. It looks like when you did the WS you knit sts that should have been purled. Pay close attention to where you are on each row.
