Patty,
I have a mini-iron and love to use it. It's great for paper piecing.
Word of caution... Don't allow a piece of fabric to lay on it while it's hot! Yep! Been there! Done that! I had tossed a chunk of fabric and didn't notice where it landed until I started smelling the scorch! Yuck! Now my fabric will have to have a hole cut in it to remove that nasty spot! It just proves that little thing gets hot!
On a side note. I invested in one of Eleanor Burns wood irons. It actually does make a difference when it's used. Amazing!
