I just finished my son's denim quilt top 90x104. He is very into western so he wanted denim and leather. The dark brown is a faux suede fabric, the light brown is a tooled leather look. Of course the denim is from repurposed jeans.The difference in the weight of the fabric vs. denim is going to make it interesting quilting. I will be quilting on my Janome 3160 QDC. I will not be crossing seams on the denim- just putting a sunburst in the squares. This will be my first big quilt to do on my machine so keep me in your prayers!
