Quote - i've tried to get around asking this, but i can't find an answer anywhere.  how do you create an edge or a hem? is there some trick or technique that addresses many edges at once?   if i wanted to just give a plane (a scarf) an edge or hem, how could i go about it?

Hmmm had much the same issue and resolved it this way:

You might try that - there are some other methods mentioned in that thread...
