Do you have a lot of projects to crank out? Stop by the store and check out the Addi Express King machine. This tabletop device lets you knit either in the round or back-and-forth. In the circular mode you can make a hat in under 30 minutes. In the flat mode you can create knitted panels about 20 to 22 inches across that can be put together into sweaters, blankets and more. 

   The Addi Express King retails for $240. A smaller version that is great for kids' hats and smaller projects costs $200.
