|I'm sure everyone has figured this out, but I thought I'd post it, just in case there's even one person who hasn't thought of it [just how many years did it take me to think of it??? I'm embarrassed to say]...
When it's really warm in the house, set up a little fan so that it blows on you while you iron. Wow, it makes such a difference. No more drips from your forehead.
I have even picked up the fan and aimed it at newly pressed fusible interfacing, still laying on the ironing board, to "speed cool" it.
Pressing is very important. I know it's been said oodles of times here at PR, but if you don't press your sewing, it's gonna look like amateur hour!
