I began with a pattern that I downloaded and cut out for shape reference, although I adjusted the size to fit my own hand when I cut the pattern pieces out of the fabric. I then began sewing the pieces together inside-out, to hide the stitching.

I initially used the sewing machine for the long straight pieces along the sides of each finger. Though the process was very fast, I had some trouble with the fabric bunching up or running off of the edges, given the thickness of the fleece and the small seam allowance that I had between the fingers. For the rest of the shapes, like the rounded fingertips and thumb, I decided to hand-sew, even though it took much longer. It was much easier to follow the contours of the fabric and I had much more control over my work, especially in areas that were at an angle, or where I had to join three different pieces together.
