One of the most popular posts I've ever written has to do with fingerless mitts.
I spent my entire life thinking of them as being the standard costume of poor, starving writers. Now I finally found out that the reason they are doing so well today is because people need their fingers free to text! I don't know how I could have missed that for so long. lol
Free patterns abound in cyberspace. If you look on Ravelry.com, you will be able to see photos of the patterns. Some of those are free and some are paid.
Another excellent resource is http://www.knittingpatterncentral.com/directory/fingerless_mittens.php.
I scanned down the list and there has to be at least a hundred patterns. The last time I checked, all of these patterns were free for anyone to use. The sister site for crocheters (and with just as many patterns) is http://www.crochetpatterncentral.com/directory/mittens_gloves.php
Allfreecrochet.com has many patterns. I don't find it especially easy to navigate, but that might just be me. http://www.allfreecrochet.com/Fingerless-Gloves
The sister site for that one is http://www.allfreeknitting.com/Hands-and-Wrists.
If you are interested in making up some of these for Christmas gifts, you'll find the basic ones take no time at all and not too much yarn. Unless you decide to work in the round, all you have to do is work up a square and sew the sides together, leaving a small opening for the thumb. They should be a smidgen smaller than you think they should be because the stitches will relax a bit with use - and also the patterns are often designed to stretch.
Happy crafting and Happy Thanksgiving,
