I am currently working on an Heirloom Baby Set by designer Nell Abshire, the Afghan Queens. In the pattern she suggests Estillo yarn which is a thin dress yarn. She tells how to do the modified e wrap cast on using two threads of yarn for the cast on. I am sure I have seen this before but thought I would share it with others that might not have seen it. This can be done on any machine. I like the finished edge and it gives body to the jacket edge. I think this would be a great cast on for the beginning of a lace scarf or any scarf for that matter that uses a thin yarn. It makes the edge stronger for tassles too if you use them on a scarf. If you use this on a scarf and want both ends the same, start the scarf and knit to the middle and take off on waste yarn. Then knit the second half and do the same. Then Kitchener stitch the pieces together.
Here are the directions and pictures if you would like to try it.
