There are no stupid questions!
In order to create a four patch you will sew two pairs of patches together first, press both of the seams to the same side, then nestle those two short seams together with one longer seam to create the unit. There will be a few stitches at the ends of the first two short seams that are within the seam allowance of the longer joining seam.

If you then turn it to the back you will see that those few stitches within the seam allowance of the longer joining seam will need to be un-sewn in order for the intersections to twirl. Most of the time (especially if the fabrics have been starched) just nudging the seams in the direction you want them to go with your thumbs is enough to un-sew those last stitches and create the twirl. If they don't separate easily, I take a seam ripper and gently pick at the seams until they un-sew back to the (longer) crossing seam which has locked them in place. From the back you should see a tiny four patch right at the intersection! Click on the photos for a closer view.
Jeeesh...it takes a whole lot longer to explain it than to do it!!
