This square is from the The Great American Aran Afghan and was designed by Meredith Morioka. It consists of an intricate center cable and a seed stitch and lace pattern as the side borders.
I finished this square last week but apparently I misread the instructions and used a needle size too large. Previously, all of the other squares I had knitted were fairly consistent as to size. In fact, all of them had blocked nicely at twelve square inches each. But this square was huge...... and I do mean HUGE! When I measured it, the tape measure revealed the thing was fourteen inches wide and fifteen inches tall.
After mumbling a few choice knitting words, I frogged the entire thing, reduced needle size, and started over. The re-knit version happily was right on gauge so I have added another finished square to the stack! Twenty five more to go!
