I too have had the same problem with scratchy embroidery until I tried a product by Floriani - No Show Mesh Fusible
This
is a sheer cutaway, works great and is so soft. This is fusible
and allows you to avoid environmentally harmful adhesive sprays and
eliminates the need for basting. the adhesive backing is activated by a
low-temp (260 degree) iron for a strong, secure hold to keep the
garment from stretching out of shape when hooping. So you can fuse on
to the garment before you embroider it or afterwards. Can also be
use for stabilizing delicate fabrics like silks, satins, taffetas and
lame for embroidery.
Hope this helps
