When teaching brand new crocheters how to make a swatch of one stitch or another, I always remind them of this.
Always turn your work away from you. When you get to the end of a row, chain one or two (loosely!) or what ever you need and then turn the work, from the needle, away from you. Not toward you. You don't want that chain to get twisted the wrong way because then you'll never find the proper spot to put your last stitch of the next row.
Plus, this way it's easier to eye that elusive last stitch that people always miss making for trapezoidal drama
