I read that poly being synthetic can melt with the iron while piecing and I had that issue...
even if cotton thread won’t shrink as much, poly doesn’t shrink at all so I was wondering if you don’t pre-wash (like a jelly roll is best not to do that) the moment you are done will it make it all wonky because the fabric did shrink but the thread didn’t ...
