Choose a pair of gloves, old or new it does not matter a lot. A pair of gloves that you were going to throw out anyways because it had holes in the fingers will best serve the purpose.
On a clean, flat surface, such as the top of a kitchen counter, lay down one of the gloves.
Mark the gloves in a place where you will be cutting off the fingers using a tailor's chalk. You can do this with the help of a ruler or by wearing the glove and marking it at the point where the knuckles start.
Similarly mark the other glove. Take a pair of sharp fabric scissors and cut off the fingers from both of the gloves. Use the markings you made in the earlier step as a reference line.
Finally, to make the gloves ready for use, you need to stitch the edges of each finger. This may be tricky if you have not done needlework in the past but still you must do it because if you leave the fingers unstitched, the gloves will further unravel.
After you are finished stitching the fingers, you have successfully made a pair of fingerless gloves. Try it on and make any modifications if necessary.
