Can anyone help work out the cable/lace pattern in this baby
blanketHelp with knit pattern
Welcome to KH!
As a starter you might try experimenting with a yarn over, k2tog alternating rows with ssk, yarn over on the right side (RS) rows. Purl across the wrong side (WS) rows.
A kind of variation on this pattern:

Could it be this?
The right side stitches look slightly different but that could be down to the yarn type perhaps. The wrong side looks pretty much the same. There is a pic of the wrong side on the link and video tutorial.
