Now we're going to make the second kind of squares.. these are the sides and top and bottom. So take the two 2.5" strips, put them right sides to right sides and stitch down one long side using a 1/4" seam. Now take that strip to the ironing board and again press closed to "set" the stitches,, then press open.. pressing the seam (for me) to the green side.
and here is the "side" strip all put together.
