Rittenhouse Needlepoint in Philadelphia has a series of posts on their blog about great stitches for needlepoint. The most recent is Paris Stitch, pictured here. This wonderful straight stitch is great both as a stitch for small spaces (use only one thread here) or as a stitch for a focal point (using two or more threads).
It has a wonderful rhythm both to view and to stitch.
One of the things I love best about Rittenhouse’s stitch of the week series is how easy they are to use for learning new stitches. The pictures of stitches are clear and show several variation and the diagrams are great. Creating a stitch sampler for yourself using these stitches ia a wonderful way to learn.
