I finished my Series 7 Thangles BOM top. However, the top has quite a few issues. I believe the problems began with using too much steam when I was pressing. So I had some shrinkage in the blocks which I did not notice. Consequently, when it was time to do the sashing and cornerstones I had a lot of problems. I used a ton of pins and had to do some easing when sewing the rows together. There are some small pleats/puckers.
I have read that some people starch their backing before layering and quilting. Has anyone ever starched (though I will be using sizing) on the top, pressed, and then marked? Will a couple of layers of sizing have any beneficial effect on the top before I layer it? I know that nothing can take the pleats out (as they are sewn in) but will the sizing help to flatten it out a little more as I press it? There is also some puffiness where some points meet.
Also, if the backing is heavily starched to help keep puckers at bay is it harder to pool when quilting?
