You can buy the fabric for these pillow cases from our shop in Etsy, Goodis or Grape Station.
First I cut the lacy bit off from one side.
Then I used the interlocker on the edges.
And attached the cut-off next to the lacy end of rest of the fabric.
The pieces sewn together.
Then I folded the fabric to form a pillow case and sew the straight edges together.
Bob's your uncle!
