It's never as easy as I think it should be. The busk is in. I followed pretty much the same steps I did to insert the other side. Attach the facing to the front panel, then fold and baste the ends. Here is a good picture of the folded and basted ends.
See how the back facing is folded so it's slightly shorter than the front so it won't show? After everything was folded and basted in place I stitched 1/16 from the center front edge then marked where the studs will come through the fabric.
I used an awl to make the holes for the studs, pushed them through, and sewed the busk in place.
And there is the new problem. Can you see it? The center point isn't as perfect as I'd like it to be, but that's not it. It's that seam at the edge of the ribbon. There is 6mm space between seams on the left side, but maybe just 4 on the right. Yuck. It's even more visible when you look at more of the busk.
I thought I had allowed a bit of extra fabric for that small 1/16 seam at the center front so I wouldn't have this exact problem. I guess I didn't. I do have a possible solution though.
If I run a thin piece of ribbon along the edge of the loop side, and bump it just over the edge on the stud side, I balance the difference out. Plus, I'll have an extra seam securing the horizontal ribbons in place. Thoughts?
