More Afghan Squares

Have been crocheting and knitting more, and more, afghan squares.  I am using these squares to learn and practice new techniques.  They are new to me any way.  Crochet stitch tried is the popcorn stitch.  Knitting is the basketweave, a diamond stitch, and a diamond weave which is sort of a lace like pattern.  The squares are either 8" or 10" and will put together with either 18 or 28 squares to an afghan.  I am also teaching the stitches I learn to my students.  Still have not worked up the courage to try a cable or socks.
