Your quilt is beautiful. Your satin stitch applique is nothing short of perfection. I just have to ask tho, why have you appliqued each section except between the orange and yellow? This has me so curious.
Just saw your last post...so I see that is where your seam is. I've never tried to satin stitch over a seam but I can imagine it wouldn't look as nice and as smooth as it does over a flat area.
