I blogged about this very thing on my site
recently and was thrilled to actually find the delft blue yarn at my local walmart.
I worked the polls yesterday for our state primary here in Massachusetts, babysitting the electronic ballot marking machine which only 3 people used all day, so I was able to get a whole scarf finished and another one well on its way. I'll be posting pictures on my site soon.
I think it's a wonderful thing to get involved in and it's nice to see so many other people excited about it too!
