I made these for the "someone special" in my life. In his line of work he needs to keep his hands warm, but possibly his fingers free. They are an adaptation from the "Magic Mitten Gloves" in the Knitter's Bible of Knitted Accessories. I left the mitten top flip back off. They are knitted from Dalegarn Falk and took just under 100g. The yarn is pure wool, so making them in acrylic would probably take less, but they wouldn't be as warm.
