This is my favorite method for gloves. Its not really a pattern, because the gauge, yarn, and number of stitches are up to you.

Pick a yarn you love. Ive used everything from super-fine cashmere/wool blend, to worsted acrylic, to a thick suede textured yarn.

Pick a hook that fits your yarn and the texture you like. I usually work these in the smallest hook possible, but a larger hook would create a open lacy effect, perfect for fall or spring gloves.

To start, figure out where you want the gloves to hit on your wrists. If you want close-fitting gloves, make a chain that will wrap around this part without streching. For cuffs, just move the starting a few inches towards your elbow and fold the excess over after you finish.

I like to work one row of single crochet into my chain before I join it into a circle; its easier to work with and reduces the chance of twisting. Just work one row, join the first and last stitches with a slip stitch, and keep working in a circle.

I work my gloves in a spiral, no joining at the beginning of rounds. I also like to use single crochet, but any stitch will work.

Keep working up from the wrist, increasing and decreasing as needed.

When you reach the thumb, arrange your work so the stitch you're working is right underneath the space between your thumb and the rest of your hand. Make a few chains to connect with the back of the glove and join with a slip stitch. This will create a circle around the base of the thumb. Work this thumb circle around, increasing and decreasing as necessary. At the end of the thumb, break off the yarn, sew the opening with a yarn needle, and weave in the end.

Attach the yarn to any stitch of the main part of the glove and continute working in a spiral. Work the fingers in the same way as the thumb.

There are thousands of variations on this pattern. You can add cuffs, make them fingerless, add buttons, ribbons, lace, bells, pompoms.... Make mittens by continiung in rounds after the you work the thumb and sewing up at the fingertips.
