Ironing help

I'm pretty sure i got this tip from the late lamented Siimply Quilts--when ironing a several of the same unit, iron the first one, then off-set the next unit on top and press that--the extra heat will help the 1st unit--and so forth.

what i also find useful, is that if i have a lot to do, and i need to smooth out the following units, i get out the ironing pad (a thick silicone pad--it came with one of my irons but i don't remember which one) so i can just leave it face down in-between picking up the units. saves on the wrist action.
