This adds to the cost but is fool proof. Attach wash-away stabilizer to the back of your fabric that you are sewing. Let it extend beyond the fabric so that you start sewing it first then the fabric that you are joining together. The stabilizer only needs to be under the part that you are sewing and the part that is fraying - probably not more than 2 inches width of stabilizer no matter how wide your fabric pieces are. After your fabric is stitched, spray the stabilizer. It will dissolve away. It will have solved the problem of the fabric being eaten by the feed dogs and the fabric edges fraying, then it will dissolve away- all for a few pennies and a few minutes of preparation.
