I made a patchwork quilt with suede and corduroy once, just large ( 10") squares. It turned out great, one of my favorites for the simplicity of it and the texture, look, great double sided, flannel backing. It is a great cabin in the woods snugging quilt. Quilted beautifully! Did nice decorative ( fall leaves) quilting on the suede squares and cross hatch on the corduroy squares.
I used a sharp needle in the size appropriate for the thread, 40 wt. Polyester thread for piecing and 30 wt cotton for quilting. Wool batting because I like the lightweight loftiness of it and it is so easy to stitch. I've also made purses, totes, and quilted jackets with suede fabrics.
I use a normal seam width and a slightly longer stitch length.
