Pay attention to the place where the stem and the bud are joined. Here, you need to make a thickening by means of the ribbon. What for? If there is no thickening, then your bud will be leaning from side to side, and this is not very attractive. It is necessary that the rose looks as close to natural as possible.
I'll share one more little secret. Floral ribbon can lose its beauty after frequent use. What can you do? Cover it with a varnish, for example, transparent nail polish.
