I am hoping that you fantastic ladies can give me some advice. My grandson first of all asked me if I could embroider two numbers on the top of the sleeve. It is very slippery material and lined, so I declined. I have decided to go the applique way and sew out the two numbers and then hand stitch them in place.

My plan is to stiffen the applique material with vilene, then hoop soluble stabilizer, slide a piece of tearaway under the hoop and stitch the numbers out.
Is this going to work? Any ideas would be gratefully received.
I have been asked to embroider the numbers in white.
