I always loved the undulating sides of some scarves.
( normally you try to make the sides of your felt flat
and definately not with waves ! )
Altough I 'd never done this before
I had a rather good idea how it must work :
so much of the end result is preordained
by the way you lay out the wool rovings.
Apart from the waves I wanted
some leaves too
I left the ends of the leaves untouched
so they would felt in with the rest or the scarf
... and this was the result : just as planned
( hmmm ... sometimes it's just your lucky day )
