This is actually more about how to make that much desired bell-shaped gauntlet with the V cut on the outside. If you want to make the gloves and a pattern is either too difficult to make or difficult to find, try what I do: Find a cheap pair of gloves you can buy, take one glove apart to use as a pattern, and keep the other glove intact to use as a guide so you'll know how the pieces fit together. Here's a pic of the pattern I use most often, I got a pair of inexpensive motorcycle gloves from Wilson's Leather. I like this particular style because it only has 4 basic pieces, whereas some styles of glove have 6 or more pieces that are very difficult to keep up with. (The intact glove is on the left. The gusset piece on the bottom is actually 2 pieces, but I cut it out as one piece to save effort. It works just the same)
When you have your complete glove, put it on and measure how long you would like the gauntlet part of the glove to be. Be sure to add at least a quarter inch all around for seam allowance. The pattern you see here is folded in half, and the narrow end is the same measurement as the open end of the glove.
The length and width of the gauntlet is up to you, but you need to decide on a size at this point because if you change your mind later and want to shorten it, it will be more difficult to do so. The next pic shows the pattern opened up, showing the curved shape you want to shoot for to achieve the proper look for a Cap style glove. The fold is to make sure it is symmetrical.
Cut 4 identical pieces of fabric, making sure to account for the quarter-inch seam allowance. Place 2 pieces right sides together; it helps to use double sided tape to hold the pieces together before stitching; pins will make holes that might be noticeable on the finished product. Figure out how deep you want the V cut (slit) to be, and mark both edges of the top fabric layer. I generally mark about midway on the length, just make sure the measurement is the same on both sides. Stitch starting at one mark, stitch around the corners and the wide hem curve, all the way to the mark on the other side. Be sure to backstitch to lock the stitches at the marks. You don't want the stitches to unravel. The pic below shows the fabric pieces stitched, the corners clipped and the hem edge trimmed, which you will want to do before turning the piece inside out (that comes later).
Use the double sided tape as shown in the next pic to join the free edges together. You are basically going to turn up one layer of fabric and put the tape down one side.
Peel the backing off the tape, then join the untaped fabric edges to the taped edges, as shown in the pic below. Make sure the seams line up exactly in the middle.
Starting on one end, stitch until you get to the center where the seams meet. Stop. Pull the needle out, cut the threads, reposition the fabric by folding the stitched edge back and then start stitching the unstitched seam together starting at the center point. Stitch all the way to the edge.
The next pic shows how you should fold the already stitched seam back. Where that seam stops in the middle is where you should start stitching that last seam. NOTE: You should only be stitching through 2 layers of fabric.
At this point, you can turn the gauntlet piece right side out, turning out the pointed edges of the V slit. I generally use a not-too-sharp chopstick to do this, but be very careful, because it is easy to poke right through the fabric.
Turn your glove right side out, and join it to the gauntlet piece using double sided tape. The V slit seam should meet up with the pinky side seam of the glove. Stitch together. The pic below shows the glove being inserted in one end of the gauntlet for stitching one layer at a time. If you like, you can stitch the glove with both layers together. I find I have a little more control doing them separately.
Once the gauntlet and glove are joined, turn the entire thing right side out. Next, you are going to finish the edges of the gauntlet. To make this easier, use a lubricant such as Sewer's Aid so your presser foot won't stick to the pleather (or leather). You can find this stuff at most fabric stores or at Michael's in the quilting section. Dab a bit on the edges and spread with your fingers along the entire edge of the gauntlet. A little goes a long way.
Machine stitch right on the edge of the gauntlet, making sure to stitch through both layers of fabric (it's easy to get too close to the edge and only stitch through the bottom layer). Go all the way around, stopping and repositioning the gauntlet as needed for the corners.
And voila!!! Your glove is done!!!! Now you get to do it one more time for the next glove!
