If you would like gauntlets that are button on, consider making a button placket and a buttonhole placket.
At the moment, this is a blog entry more of ideas than pictures–sorry, visual people!
Here is one idea: A rib will make the plackets flat and they will require no hem. A 1 x 1 is most simple rib and allows you to work with the 56 stitches without worrying about beginning and ending with the same number of stitches. A rib offers structure, too, and this way, the gloves are completely reversible in all ways. I recommend both plackets being 5 – 6 rows.
Buttons: I’m thinking 3/8 inch in diameter. Space evenly. Count carefully.
Button holes: For small buttons 1 yarn over and an ssk will make a button hole. Knit the yarn overs on the next row. Space as for buttons. Count carefully.
Bind off all stitches for both sides using a flexible bind off. For this bind off, cut yarn leaving a considerable tail, thread on a tapestry needle. Without turning the work, put needle through first two stitches (knitwise) and then back through the first stitch (purlwise) and take the first stitch off the needle. Repeat these steps until all stitches are bound off.
