I also use wash-away film type stabilizer as a topper when satin stitching (not during the applique process).

After I launder the applique fabrics, I press well and then apply a fusible webbing. I like Heat N Bond Lite. It fuses well but does not gunk up the needle. Steam-a-Seam - even their "lite" products - will gunk up the needle - it does not work for me at all. It's great for fusing things but don't use it in machine embroidery! Take my word for it. Some designs have so much stitching that a fusible webbing may not be necessary but I think it's a good idea to use this in children's clothing.

This picture shows a portion of the applique, just after it's been tacked down.
After this tack down, I remove the hoop from the machine and cut away the excess fabric. This is where the fusible webbing comes in. I use my Clover mini-iron to set the fusible webbing in place. By doing it at this step I avoid over-pressing the satin stitches.
