When all is said and done you can go back and chain them up the row by hand. You can see them looped over the hook...which is really only there to hold the swatch down.
What I didn't like about the swatch is that the pattern calls for the stitch to start about four rows up. it leaves too gaping a space to look good as far as I am concerned. If I make a sweater using this I would start on the second row. Also note, I am using the Foundation Row which gives Tunisian better flexibility at the bottom rather than the tight non-forgiving normal bottom of a Tunisian fabric.
