I bought my wife a new headcover and she is pretty pleased with it, so I thought I would pass on the vendor. It came from Garlands of Grace and they have some pretty nice headcovers for sale. I got her a longer one made from a lightweight chambray that is more of an "everyday" covering. It is made very well and fits very nicely. So if you are in the market, you should check out Garlands of Grace!
(if you are curious, this is the headcovering I bought her from their Etsy store)
