Pillow - Fabric Framed versus No Fabric-Frame

This hand-painted canvas by LEE was blocked and then sewn into a pillow.  The pillow at left has a knife edge with no border, the pillow at right is sewn with a mitered-corner fabric-framed front knife edge.  The left pillow was much smaller and the customer decided that she wanted it redone with a fabric-framed front to make a larger size.  Both have zippered openings and custom boucle twisted cording trim.  The finishing fabric is burgundy velveteen.
