Here's another little tip - decide on the heel flap pattern you like and stick with it. Don't waste time deciding which type of flap to do - pick one & stick with it! When you are someplace you can't knit (can't imagine where that would be) you can explore the various options for heel flaps. Use your knitting time to knit those socks - not to make design/style decisions! ;)
