I have not sewn with minky but if I were you, I would consider cutting the squares apart and squaring them up by making them smaller. I would then sew with the 1/4" seam with the walking foot. And I would replace the minky with a pink cotton. I would add a border if I needed it bigger. I know I saw a discussion on here about sewing with minky. I would look under advanced search. Maybe you could use minky for the backing. Welcome to the board. You will learn so much here.
