Thank you everyone for you tips. So many good ideas! I loved the idea of pulling it like a draw string. I would never have thought of that. And if the yarn was shrinkable (I don’t know if it is) that would also be a perfect way of making it smaller which would also make the hat warmer. Thank you for offering your support Sarah, perhaps I’ll call you next time I need to rip up something.
As you can see I went for the rip up solution.
I think I have said what I’m about to tell you before, but a good thing can not be repeated too often. Some years ago an old Spanish lady shared her crafters wisdom with me. This wisdom chimes inside my head every time I have to rip up or redo something. She said:
“Once you finish a project no one is going to ask you how much time it took you, they will only look at the end result”.
She was wise
