Hyacinth Stitch

Sample knit with worsted weight yarn on US 10.5 needles, Knitter's Pride Cubics

I so love this stitch!  While I wouldn't say it is hard, it is a little tricky - purling 5 together!  You can make this part a bit easier by working the preceding rows a bit more loosely than you normally would, use needles with pointy tips, give the stitches a little wiggle once the needle is through them, and use a wool yarn.  Wool has a bit of spring to it, and will give slightly as you knit.  You can use any yarn you like of course, but wool can be a tad easier to manipulate 5 stitches at a time.  This stitch also has super sloppy sides.  I would recommend adding several stitches along the sides for a border to neaten it up.  The bottom makes a pretty edge as you can see in the picture.
