I've tried various things and am just happiest with the hand finished edge made with French Fold Bias Binding. I wash my quilts and know the edges do hold up. For years I really tried to simply the binding process especially since my hand work is agonizingly slow, the needle threading hard on my eyes, and so on. I also keep telling myself "a kiss with every stitch" to keep from swearing or sewing in tension to the project... I just never got quite the results I wanted with machine and decided to go back to my old way instead of learning new sewing skills.
But of the techniques I used, wide decorative stitches are also a possibility especially for baby quilts. This is the time for the repeating flower motif or whatever strikes your fancy. You might need a fairly hefty machine sometimes to get over the corners. Keeping the design along the inner edge of the binding will hold down whatever is going on in back.
Not an answer to your question but I typically make wider than usual bindings, it is my last chance to add fabric to a top and I am typically using something coordinated or contrasting. For my queen sized projects I also use a thicker batting than currently popular, and less quilting (again than is currently popular), and the wide bindings seem more appropriate. I usually cut them at 3" or larger, but sometimes it might depend on the width of stripe or other design element. I don't trim my back/battling until after the binding is sewn on at the normal 1/4", and measure from the seam out for the width I want. Then I cut the depth I need for my wider binding through the batting and backing.
