One of our granddaughters is married and living in Florida. Now while one usually thinks of Florida as hot and humid, this year they have had some very cold weather so this granddaughter bought herself a pair of mittens. They are open at the palm to allow the fingers to be free if wanted. She informed me that while buying them she thought, "My grandma could make these." A call to arms! I just finished the mittens, and next week they are on their way to Florida. I resisted the temptation to embellish them with a pretty heart on the back as she is now twenty one. Here are the finished mitts.
I tried several internet patterns but thought them too bulky where the cap went over the fingers and joined the mitten. Came up with this design. It is an old one but available for free on the net. You can find the pattern here
The pattern only comes in one size, woman's. However, making the cap for the fingers is a simple technique, and one should be able to convert any mitten pattern of any size.
