What lovely tops you have created Bodgeitandscarper. Now whilst this may now be too late for you, the latest edition of Threads magazine No.205 October/November 2019 has a four page article about embroidering on velvet and this goes in choosing a suitable design, selecting a stabilizer, using a topper, using wash away, using cut-away and tear-away, hooping the velvet, stitching the motif, and finishing the embroidery. Ironically they could have been looking at your tops, as this top has the embroidery where you have yours, and then there is a horizontal seam and skirt to top of legs, long sleeves.
