I am seeking advice and/or recommendations regarding barrier protection used on the underside of embroidered garments where these are in direct contact with the skin. For example, when designs are embroidered onto childrens t-shirts, the underside of the embroidery can be an irritation to delicate skin (I would imagine that this would also be an issue for ladies). I believe that there is an iron-on product that is fused over the embroidery underside, providing a smooth barrier against the skin. I would very much welcome your advice, guidance and recommendations as to product availability. Thank you.
