So I decided to experiment during my lunch hour yesterday with the appliqué.
I tried a thin row of back stitch along the edge and it failed as expected. It will not hold up to the strain, the silk shredded.
Small whip stitches held up to me pulling on them.
Added some wool roving under the silk to see if I liked it padded, ( jury is out still ) and tried out the medium size of the seed pearls.
Overall happy with the outcome, and somewhat relieved it will not take an eternity to do the appliqué.
