just to make it clearer my questions are:
1. do i make a slip knot? or just attach the yarn like i would do in any other attaching of yarn?
2. the 9 sts and these new 12 sts - do they need to be joined in any way or will they be seperate and then knitted together in the next row (the instructions fo rthe next row are: k12 then k9 sts from holder. 20 sts)
