When you stabilize backing fabric before attaching your appliqué you give your appliqué a very professional look. It does this by;
The end result is very pleasing.
There are several methods that can be used to stabilize your fabric.
Tear Away This can be purchased from your quilting fabric shop. I find this method less than satisfactory as it tends to pull the stitches when you are removing the tear away.
Plain Newsprint This as above has similar drawbacks to tear away. It is also another layer added making it difficult to manage while sewing.
Spray Starch This is my preferred method. Most supermarkets stock spray starch, making it readily available.
Spray Starch Method:
I find some fabrics only require 2 applications but others may require 3. By the time you have assembled your quilt top your spray starch will have all but gone. If you decide to add further appliqué once finished and need to add extra spray starch then spray this onto the wrong side of the backing fabric.
Great! With your fabric now stabilized you are ready to learn how to use steam-a-seam to make the sewing on of your appliqué design a breeze!
