It's easy enough to make a filled or solid design like this. But it would not be wise to embroider a design on top of it without removing the underlying stitches - it would make a bulletproof embroidery. You would really be better of to make an applique on which you can embroider anything you like.
Are you looking for an applique type design? If so, many machines have those built in - both of my Brothers do...?
aren't these just outlines?? I have a Brother 900D I need a solid design.
