Hi Everyone!
I am writing a pattern for my skirties that i make
i make the soaker first, with a row of purl stitches where i want the skirt to attach, and than i pick up the purl stitches (well, the lower ones)
i made a little image incase i am not describing it properly...

so i have mostly stockinette (V's) and than the brackets is the purl row... i only pick up the red stitches
how would I write this pick up into a pattern?
