"What I wear and how I wear the headcovering", posted by "Country Mom" at blogspot, explains - not the why, but - the "what" of her decision to cover her head as a Christian, in obedience to 1 Corinthians 11. She shows pictures of how she ties up her bandana, as well as photos of friends who also cover. (automatic radio begins playing at this page - the player is posted at the bottom of the page, if you wish to click the stop button).
Also, please check the Christian headcovering blogs (linked in my sidebar at the right) for "Free to Cover" and "Light and Good Order", who often post their own examples of how they choose to cover, using scarves, turbans, snoods and all manner of home-made or -styled coverings. :) Just scroll through their past postings.
