This dress is a gift for a friend. Base fabric is wool, seam finishing and embroidery is mostly wool. The magenta embroidery is linen because it was the perfect color to match the underdress. The applique is 2 colors of linen. Seam finishing is done with long arm cross stitch and applique is blanket stitch. The straps are strips of the same wool fabric folded so the edges are inside and finished with blanket stitch.
Here’s a photo of the start of attaching the bunny, with a bit of seam finishing visible.
And the finished dress modeled by the recipient:
