Firstly you need to work out what colour yarns to work with. I chose white and navy blue basically because they were the same colours as the chart in the practise swatch document, easier to work from the chart that way. So 2 yarns, ideally one a white or light colour and the other a blue or dark colour. I have my yarn a (the background) as white and yarn b blue. Next cast on the number of stitches, the pattern repeat is 11 stitches and then you need the 2 selvedge stitches. So that’s 24 , 35, 46, 57, 68 etc stitches. I suggest 35 so you do 3 pattern repeats, enough to get a feel for the pattern AND if you want to turn this into a square you can do by just knitting more rows. So cast on the stitches in your background yarn a colour and knit 2 rows.
Then row 3, this is the interesting bit. Change to using yarn b and knit across the row , slipping stitches purlwise as you go along. The stitch you knit at the start and end of the row anchor that yarn in to the fabric. You need to make sure that the yarn goes BEHIND the stitches that are slipped. So the strands sit on the wrong side of the work.
If you are working from the chart you will see there is no row 4!! But you will see that there is a row 3 and row 5. Well that’s because row 4 is exactly like row 3 where you knit the stitches that have already been knitted and slip the stitches that have been slipped. Again slip purlwise and keep your yarn strands at THIS side of the work (this will involve you actually moving the yarn across from the other side).
Row 5, change back to yarn a (in my case white) and knit across , skipping the stitches that need slipping and end with a knit 1. Make sure the strands are along the BACK of the work. Row 6, as row 5, but now make sure the strands are FACING you.
Row 7, in yarn b (navy blue in my case) k1, then work across slipping the stitches as you go. Strands to the BACK of the work. Row 8, again like row 7, strands this time AT YOUR SIDE. Take a look at the wrong side, does it look fairly neat?
I've finally got to the end of my little pattern (Row 14 done on the top photo). I decided to carry on to make a border pattern by repeating rows 3 and 4 .
