YES, it can be done! I learned this method from a wonderful class with Sharon Schamber. You can use starch and heat to reduce wobbles and waves from any quilt top, border, or block! I did this last week with a beautiful, vintage top. The quilt was machine pieced and hand appliqued in the blocks.
This is what the block looked like before I created the magic! There was at least 2 inches of extra fabric in the center. After I sprayed the block and ironed, it was almost flat. I was able to start stitching at this point with NO WRINKLES OR CREASES!
The final block looks like it was perfectly flat to begin with!
As usual, I used my favorite quilting rulers for lots of ditch stitching on this quilt.
Now, if you’re still wondering how this whole starch and shrink thing works, watch this quick video. I learn by watching, so I hope the visual helps you too!
