We have developed a method for obtaining highly accurate distances to
open clusters by main-sequence fitting using optical and infrared
colors.  We present new distances and estimates of reddening and
metallicity for several open clusters that contain Cepheids.  These
clusters have 2MASS photometry that reaches well down the main
sequence.  We discuss random and systematic errors in the distance
determinations, and the implications of our results for the Cepheid
period-luminosity relation.
