I like the tear away paper stabilizer. It really helps reduce puckering.

I use wonder under and I do the blanket stitch by hand, I love to stitch and listen to the tv

You can use a tear away paper-purchased, copy paper, or even paper towels...they tear away very easily. Satin stitching needs to have some stabilizer or there will be distortion because of the close together stitching.

A friend of mine and her mom used to make sweatshirts with applique stuff on it for craft sales. You'll never believe what they used underneath.....(on the back side of the bottom fabric..) that lightweight slick paper that comes in the Sunday paper that has coupons on it. She says it works great. You can try.

When I did appliqued t-shirts and sweatshirts for craft shows, I always used copy paper. I worked at a school and there was plenty of paper in the recycling boxesfor free! It doesn't matter is it has printing on it. Have also seen notebook paper used.

I starch or use freezer paper or fusible web. I use the blanket stitch I find it much better for me.

I love to applique and I only use the machine blanket stitch or hand blanket stitch and have never had a problem. I use Mistyfuse to adhere the applique to the fabric. I think that satin stitch IS the cause of your problem. Can you rip it out and start over?? I've not used satin stitch but I know it makes the thread very thick.

lisa+lori have the answer for you

I also use the Steam a Seam, and put tissue paper under the background fabric. It tears off easily and helps with your problem.
