First, I'd like to thank everyone who made suggestions after my last post about stitching a 3D petal. Thanks Karen, Rachel, Stitching with Kittens, Elmsley Rose and "Anonymous"! I really appreciated your input. Six heads are better than one, right? : )
For all subsequent attempts I've used Rachel's suggestion of split stitching the edge first to stabilize the linen.
For my second attempt I tried buttonhole stitch around the edge. This looked even worse than the first attempt. My kitten made off with that petal so I have no photo yet. I'm sure it will surface at some point so I can photograph it. The buttonhole edge, which is what secured the metal thread to the petal, sat away from the linen in an uncomplimentary way.
Jane uses buttonhole or overcast stitch to attach the wire so no difference there. One major difference is she uses a thread that closely matches the fabric. Also, although I've not seen the wire she recommends, I suspect it's much thinner than the DMC Memory Thread.
So for my third try... I decided to change the wired thread from DMC Memory thread to a finer wire. I chose 371 wire. I thought the finer wire would allow me to trim closer to the edge stitching, which it did.
First 2 photos are my 3rd attempt. It's better, but still doesn't please me.
4th attempt: I switched to white thread for the overcast. Still a tiny bit fuzzy in spots. More importantly I lost the visual impact of the colored edge. It's something I could fall back on if it becomes necessary.
I only stitched enough of the petal to give me an idea of how it would work. The Petal Thief kindly modeled this petal for our photo, incase you're wondering what's in the background. I also used scrap linen with writing on it.
I am waiting for an order of even finer metal thread to arrive. I also think that it will have to be attached after the petal is cutout as Anonymous mentioned doing. That will necessitate overcasting the linen before cutting it out to prevent fraying, and then again to attach the wire after cutout. Elmsley Rose suggested Tailor Buttonhole and I may try that, too. I've only done it along a straight edge though so will need some practice on a curve.
