This one is covered in pre-washed fabric - it has free-motion, hand quilting, grid and applique, same as the unwashed sample
I had some interesting results with these. I should point out though, that the covering fabrics are not the same (silly mistake on my part). The unwashed sample fabric is a rather heavy and stiff calico, while the washed sample is covered in a thinner, softer calico. This will have a large effect on the results, and in fact I'll have to do it again to get a proper comparison. But for now, this is what I ended up with.
On the right is the one covered in pre-washed fabric.
You can see instantly that the pre-washed sample is a lot less wrinkled and puckered and the stitches are clearer.
After washing the unwashed sample shrunk 1/2 inch
The pre-washed sample shrunk 1/4 inch
Of most concern is the effect on the hand quilting. The unwashed sample wrinkled and puckered so much, that the design for the handquilting is completely gone - it just looks like a mess.
That is supposed to be 4 heart shapes!??
Here's what it looked like before washing
The pre-washed hand quilting fared better.............
This was quilted with grey thread
