Minibarn thank you. I do the embroidery if it’s a wedding gift using rayon never polyester thread. There’s another batting called warm tater batting which has been replaced by warm and plush ya might try. Also microwave safe. Just wondering if how you assemble makes a difference. I stitch down batting to the top fabric then repeat with the bottom fabric darts and all so it’s a sandwich with nothing in the middle, trimming the batting back about 3/8” around the top edge before stitching together and turning. Then I Elmer’s glue the opening and topstitch close to the top edge. Don’t know if your method is different. Just sharing mine.
