I used a washaway stabilizer plus a really heavy starch when I did redwork for a quilt. Starch until the fabric is really stiff, then put the washaway on back for the embroidery. You don’t need to remove the stabilizer when sewing, though you can trim it if you want. Note this only works if you can wash the finished quilt on warm. I have had inconsistent results with washaway stabilizer and cold water.
