I have to agree with this. The purpose is to be 3D...a little structural change for a "pop" that will disappear if you quilt on top of it. Just my opinion, howeever!

I also agree with mad quilter. If it is a flange it would be like sewing over piping.

I've put one of those borders on a few quilts and have always sewed them down. The reason I put them on this way is if you want the look of a thin border, this is easier than adding a 3/4" piece of fabric and then trying to get a crisp 1/4' finished border. I once decided to not sew it down and quilted the quilt on my frame. Exercise in frustration as it got "caught" under the FMQ foot 100 times..... well maybe 20 times.....

I quilted a quilt with one of those for my aunt. I very carefully pulled that flange back and quilted right up to the seam but I never quilted over it. Well, I did once but I removed those stitches. If you sew it down I don't see why you couldn't quilt over it. That way your hopping foot never gets caught.

After looking at the border patterns you are possibly wanting to use I would actually get out some paper and make myself a pattern of the butterflies and use them. There is paper you can use from golden thread that is made for that purpose and it sure would carry on your theme. You could even get the thin template material and cut out your own pattern and mark it on the border and free hand sew it. I do that with some of mine on the longarm.
