I wrote this as i knitted it so if you find any mistakes let me know!
The cast on sts are the top of the shawl, the cast off will be the bottom. This is a very basic pattern that you can then embellish - i used an eyelet pattern on random rows.(k2tog YO) The first stitches should not be slipped (as i usually do when knitting) but knitted.
You can use any yarn you like with its corresponding needles. there really is no gauge
You can also knit it to any size. Just remember that the final amount of stitches you have will be its width and the number of rows you knit will be the length. You can check that on a swatch and calculate accordingly
Cast on 7 stitches.
Row 1 (RS): k2, yo, k1, yo,place marker k1 place marker, yo, k1, yo, k2.
Row 2 (WS): K2 , P to last 2 sts knit last 2 sts (and on all WS)
Row 3 (RS): k2, yo, k to marker, YO, k1,move marker YO, k to last 2 stitches, YO, k2.
and so on
So to give a quick recap.
The 1st 2 sts of every row are always K followed by YO
Before the 1st marker, there is always a YO - the stitch between the markers is knitted as it presents its self (k one side P the other) and after you slip the 2nd marker there is always a YO.
On the Purl side, its always K2 and purl to last 2 sts - K2 (no increases )
Using your swatch you can calculate the size you would like to make. Amount of sts = width, amount of rows = length
Hope this makes sense!
