Emma S, if they sew the strip sets, then press one set's seams towards the outside strips and a second set's seams towards the middle one, then cut them. I think they'd sew together nicely. pressing the seams open would work too. Sorry for all the editing, I have trouble putting what I see in my head down so that it sounds logical.
