1) What do you pack to knit?  Last time I had some crocheting with me, but combination  holiday with children does not allowe so much knitting/crocheting.  Maybe a pair of socks would be ok this time.
 2) What do you hope to shop for?   Lockal made yarn ,  sweets, maybe even some books of local traditional knitwear.
Bonus: Where would you go on a "knitting holiday"  I'd go to Iceland or to Faroes ( Färöar).  I have been in Japan.. so..
