I didn't have a pillowcase but I had this old fabric. I think it might have been a bit stiff for this but oh well. I used this tutorial from Red Instead blog.
a little big huh? I took in the sides a few inches and then it fit pretty good after.
I like the look of this dress over jeans and a top. It should fit her for a few seasons too. Do you like that hat? I traded this Etsy seller some socks for it. If you wanted to purchase a hat like that it would cost you 10.00! Isn't that crazy cheap? This size was for a 3-12 month old and it barely fits my girl but she won't let me take it away.
