Painted Fabric - black eyed susans before stitching

Here's a photo of my black eyed susans painted onto fabric.   I don't worry about a lot of detail because the stitching will take care of that.  I think I will add the backing first and stitch through the layers.  I haven't quite decided whether to add batting or not.   As I said before it makes the piece a little thick for framing under glass.   But it does add some contours to the design when stitching through 3 layers.  If I do add batting I will probably frame it without glass.
