I attach alot of ribbon to the dresses I make. I usually pin the ribbon over the middle seam where the bodice attaches to the skirt. Centering the ribbon there. I pin it on and turn the ends down so that when I sew over the top they are caught in place. If you are making the kind of dress that has the velcro closures underneath, just lap the ribbon over the edges and sew all at once. Take the pins out once you have done one edge so that the ribbon doesn't pull too tight. When you sew the velcro on it will usally catch the ribbon again on the edge. If you make bows I use my machine to sew them on by either pulling back the center a little and stiching on the sides. (that way the center loop covers up the seam and it stays in place better than hand stitching, also faster) or I make a double layer bow and pull back one layer and sew the second layer to the dress close to the center. That way the top layer covers the seam and it is really secure. You have to do both sides on that one though.
Hope you can understand this and it helps!! Good luck!
