For these, I used the same pattern I used to last year to make a pair for my yarn mentor. This pair was for a woman with smaller hands who likes to work outside. So, I made them slimmer and in a dark color that wouldn't show much dirt. As it turns out, she told me she's worn them inside to read and type when it's particularly cold. The yarn I used for this pair was Caron's Simply Soft in Dark Sage.
This pair was for my brother, who has very large hands and drives a lot. I find that fingerless gloves are perfect for driving. I knew he'd prefer something basic for the color, and it doesn't get much more basic than a nice, neutral black. In this case, I went with Caron's Simply Soft in Black.
One of the great things about this pattern is that it's easy to size. To make them longer and wider for bigger hands, you just begin with a longer starting chain and work more rows. For a smaller hand, reduce the starting chain and work fewer rows.
