Carla & Hilly (the combo that is The Dutch Knitters) have written a wonderful book about Estonian mittens titled Warme Handen/Warm Hands. It is a bilingual book; in Dutch and English. Well, maybe trilingual, since it's also about Estonian mittens.
I began a virtual friendship with Carla 6 months ago and finally met both of The Dutch Knitters in person at the conference. We sat together in front row seats at the conference and later that day connected at a kohvik (cafe) over beer and cider.

The conference was a great opportunity to make real friends out of virtual friends!
