Recently I did a Downey Child's Quilt. The instructions said to hem it on the sewing machine because it would get hard use.
On another king size quilt, I prepared a bias double fold binding, stitched it to the top, folded it to the underside, making sure I cover the stitching by about 1/8-1/4 inch. Pinned closely and carefully but starting the pin from the back on the seamline. Using this as a reference point, I then stitched in the ditch from the front. I liked it! Silvia
