What size scarf for purse?

  1. I did a search on scarves, and I came across some lovely pics of you ladies wearing purses with scarves tied to the handles. However, no one really talked about what size scarf they were using. Could those of you who put scarves on your bags give me an idea of what size you use? I am looking at some cute scarves on eBay, but I am unsure of what size to get. Is the traditional 35" square too big? Thanks for your help!
  2. I usually tie and Hermes Twilly on my purses. It's not as big, but still looks cute.
