Has anyone taught the side to side scarf?  I'm wondering how you handled teaching the 2nd and 3rd rows in the class time frame when there are 170 stitches per row.  I first taught the stitches and then had her start the scarf.  We ended up starting the 2nd row before the 1st row was done.  She did about 10" of the 2nd row then turned and started the 3rd row.  She'll have to take it out at home or start a new scarf.
