Left over yarn from Woodhaven mitts. Making a larger version of my mini-mittens.
On one pair of mittens, I used US Size 6 or 7 for the entire mitten.
On the second pair, I used US Size 6 for the ribbing on the cuff and then increased to US Size 7 for the remainder of the mitten. I think using a smaller size needle for the ribbed cuff makes the shape a bit nicer.
I can make quite a few more pairs with the left over Berroco Boboli yarn I have. Love the colors in this yarn, although this yarn is a bit splitty.
Edit 06-13-2013: made 4 pairs now all using left over Berroco Boboli. Love the colors.
