You could use a towel on your dinning room table, with that used iron and it would work the same.
Super idea! I'm a little worried about damaging the table (the veneer is bubbling up in places) but a few layers should be good if I'm just making bias tape...which is my LEAST favorite part of the quilting process! Now I just have to get all the textbooks OFF the table :P
Where there is a will...there is a way! You go girl!
