Lukeje, no one answered you, so I will tell you what I think she did on her special center blocks, was her center 10 minute block was a white one, and then she fussy cut her underwater fabric and put it inside the white center (after it is all sewn) and then turned over the edges and sewed them down, making a very cute baby quilt. Now a story from me: When I made a 10 minute block with a directional middle square, I fussed and fussed and fussed some more and then realized, that since the back ground squares were all the same, I could just turn my block until the patter was the way I wanted it--(hanging my head in shame for something so simple)
