You might see if you can find the show online. They did a show on this method a couple of years ago. On one of the quilts they shared, they had covered the seams on the front with wide ricrac. They also suggested using ribbon would work.
It might be show #1511. There wasn't a picture, but the supply list called for galaxy wide ricrac. I don't subscribe to their site, so I don't know if it's a show that can be watched or not.
