Foundation Row - Edge the pillowcase using blanket 1cm down from the edge and the stitches 1cm apart
Join wool into any blanket stitch using a sl st. I always joined at one of the seams.
Row 1 - 3dc into each blanket stitch, join row end with sl st
Row 2 - 4ch, skip 2dc, htr in next dc, * 2ch, skip 2dc, htr in next dc. Continue from * to end , sl st in ch2 of beg 4ch
Row 3 - As row 2
Row 4 - 3ch, sl st into the sl st made to join the end of the last row, * 2dc in 2ch space, sl st in htr, 3ch, sl st into previous sl. Continue from * to end.
I hope this makes sense to anyone trying to follow it and if you find any mistakes please feel free to let me know
