Anyway, the actual question is about the thread type I'm using to hand-piece a quilt top. I've been using 100 % cotton thread and have pieced about half my blocks with that. Unfortunately, I'm about to run out of thread. I do, however, have some polyester (or maybe it's a mix of polyester and cotton, I'm not entirely sure) thread I could use. Will this matter when I piece all the blocks together? Like make the top 'pull' in some places or otherwise look 'off'? Or can I just switch without consequences?
If the thread shrinks at different rates when washed, there may be a difference, but probably not too much.
Is there a way to test that? I know you can test bleeding and shrinking of fabrics by putting a bit of the fabric in hot water and letting it soak for awhile, then letting it dry. Could you test the shrinking of thread in the same way?
