I found this sheer ribbon that match very well and I went with the button embellishment, actually it is two button I had a small silver button that fitted perfectly inside the larger purple button. The colours didn't photograph very well but they are purple and silver.
For something different I did the inside of this card using the Martha Stewart border punch some scrap card and a stampin up stamp and punch.
