Here's a fast and easy pattern for mittens or fingerless mitts to fit the 3-6 year old set. This is a perfect last-minute gift or charity project.
These mitts and mittens work up really fast, because they are made with worsted weight yarn, on size 7 needles, and there are no fancy stitches or fiddly shaping. Since they are sized for small children, I've included a built in cord to connect the mittens to each other (That's something you can do with any mitten pattern!). There's also minimal distinction between the cuff and the palm, meaning that the mittens can grow with the child for a little while.
No yardage requirements are given in the pattern, because there are too many variables to take into consideration. That said, these mitts and mittens use very little yarn. The mittens I made for my 3yo (the red ones in the picture) took less than 100 yards. I also made a pair of striped fingerless mitts for my 6yo (not pictured) that used up little bits and pieces of leftover worsted wool from my stash. The mitts shown in the picture below were made from less than half a skein of Alpaca Twist from Yarn Bee (yes, that's a light bulky yarn, but it still worked). I'm estimating that those mitts took about 65 yards to make.
