I finally figured out how to make fingerless gloves using a round loom! I thought I would share my tutorial on it.
What you’ll need:
Smallest round loom (for my set it was the green loom)
loom hook
crochet hook (any size)
yarn (double or single yarn)
For my gloves I knitted with two strands. However, you can do this with only one yarn/strand (if you are doing it with just one yarn please refer to the notes at the bottom of this tutorial). To do this tutorial you will also need to know how to make the following stitches: knit stitch, purl stitch, and how to bind off/single crochet off (all of these stitches have been linked to YouTube tutorial videos for your convenience).
To begin you will wrap all the pegs once using the basic e-wrap method. Then begin the second row knit 2 pegs, then purl 2 pegs. Do this for 6 rows. This should create a ribbing effect.
Knit stitch 5 rows.
After the 5 rows, you will begin the thumb hole. The thumb hole is made by knitting from peg 1 to 24, and from 24 back to 1. DO NOT KNIT BETWEEN PEGS 24 AND 1. Picture example:
beginning thumb hole:
almost completed thumb hole:
completed thumb hole, beginning to knit the body of the glove:
Knit back and forth 6 times to create thumb hole (back and forth counts as 1).
Continue knitting around for 36 rows or until it reaches desired length.
You will begin the end ribbing at this point. Knit 2, purl 2 for 6 more rows.
Then bind off/single crochet your project. Makes sure you tie off the ends well.
Now you’ve finished one wrist warmer! You will repeat this process for the second wrist warmer. Then you’ll have a pair! 
If you do use this tutorial for your wrist warmers to sell, I do ask that you give credit back to my blog or this tutorial. Simply add “Pattern by Melli’s Mish Mash” and if possible link back to this post. Thank you!
Side Notes:
Note 1: If you find the crochet/binding off part is too tight for your upper arm, do the pattern in reverse, and finish off with this portion as the finger part! This may help open up the other side and may fit the arm better. You can also use different loom sizes depending on how big or small your arm is. If you want to go smaller, using a flower loom would be the next option!
Note 2: If you are using single yarn you will need to extend the body of the glove by doing 54 rows. When using the single yarn the stitches are much smaller, therefore the body of the glove will not be as long as intended when done with double yarn. For the thumb part you will knit back and forth 7 times instead of 6.
Note 3: From finishing the thumb hole to the next part of ribbing, knit 8 rows when using a single yarn.
