Well at least for me! I want a tall bookcase for all of my knitting books. I have some on a shorty and some on a shelf in the closet. I want one that will hold all of them so I don't have to stand on my head to see them. I've picked one out from Oak Express.
Other things I would love to have under the tree if I was a knitter:
Gift Certificate from the local yarn shop
Interchangeable needle sets from either Knit Picks or Chiagoo (red lace)
Roll up blocking board
Flexible blocking wires from Churchmouse Yarns and Tea
Sock Blockers from Loopy Ewe in wood
Oh Snap bags from Namaste
Better Buddy from Namaste in our favorite color (I bought my own already)
A really nice pair of scissors for knitting bag
A Vera Bradley Tote Bag for knitting
Knitting Books - will talk about those tomorrow
Oh, there are so many more things it would be wonderful to receive as a knitter, if you need some more ideas check out Stephanie's recommendations, she is posting them all month long.
