I've been wanting to make a serger scrap mat for a while and finally got this far (I haven't put on the black border yet).
I tried to make a quilted sewing machine scrap mat, but it was a disaster. My quilting may not ever happen on a large scale. :-)
The second photo is to give you a small glimpse in how the serger looks while sitting on the mat.
Some lessons learned: Add a plastic type of fabric or bag inside the scrap bag for even easier cleanup and I am just not good at quilting, so this one had no quilting. My first attempt did have some quilting, but it was bad.
