Ultimately, I want to make mirrored ribbons, wider at the bottom/furthest from the bow-knot. I created one mirrored bezier curve and rotated its duplicate (with the 3D cursor) at one end of the curve; I then made another curve (random shape for demonstration purposes) spanning the maximum width between what will be the sides of each ribbon. Is there a way to bridge the side-of-ribbon edge loops with the third curve, rather than the shortest path between points? Or is there a way to vary the extrusion width of ribbons generated using this method prior to converting to mesh (after which I know I could use proportional scaling)? Thanks!
