What ____ do you use?

Last time I discussed what thread I like to use.  Another question I always get is "What color thread do you use?"  The answer to that depends on what the quilt is for.  If I am making a utility quilt or a quilt that's going to be used, then I normally stick to a neutral thread, either tan or grey, just depends on the fabrics in the quilts.  Now, if I am making a quilt for a competition and that will be judged, I match my thread to the piecing.  Yes, that means I may use several colors of thread in one quilt.  I find that is the best way to hide the thread used for piecing.
