You don't want to risk scorching your quilt blocks when you iron them.
Although ironing covers and pads might not seem important, their characteristics matter quite a bit for quilters.
You want a surface that allows you to shift fabric easily and keep it smooth and flat.
The best ironing board cover and pad will work in conjunction with your iron to deliver a quick press that does not leave a grated impression from the underlying metal board.
A good cover also prevents scorches and water stains on your lovingly crafted quilt.
