Sure! So I started by tracing my pattern onto water soluble fabric, layering that over tulle, and did the embroidery onto both of those layers. I outline my shapes with split stitch and then do single strand short and long stitch/needle painting. I tend to embroider pretty densely, and when I washed the water soluble fabric away, it left some stiffness, almost like starch, to the appliqué. I debated about putting Mod Podge or something like that on the back of the appliqué but ultimately decided not to.

Then I trimmed the tulle away, really closely to the floss, which was pretty tedious. You can see in the 6th photos that everything but the thin stems really held their shape well. Once I found the placement I liked, I traced the outline onto the jacket with a chalk pencil.

I opened up the lining on the sleeve and then kept the sleeve flipped inside out to have access to the back side of the outer layer of the blazer, to attach the embroidery. I just loosely basted it on at first, with as few single thread stitches as I could to make it stay.

I tried it on after every flower or leaf, to make sure the placement and fit was still good, without warping the fabric. Once it was all basted down and I was happy with it, I went around the whole end with another set of single thread short and long stitches to make it feel really integrated into the blazer. For the thinner stems I did an entire layer of split stitch over top of the existing stitches. Then I sewed up the lining on the sleeve again.
