A big ironing board would really help. I usually split my fabric by the
yard then starch and press. When I starch I put my fabric in ziploc bags
and keep in the fridge for at least 24 hours...flipping the bags half way
through. That helps distribute the starch evenly. When I'm ready to
press, I remove the fabric and put them on some towels to absorb
the excess starch. When it's damp...then I go ahead and press.
I use a silicone sheet to keep my iron clean. I start in the middle and
work my way out. Press, don't iron back and forth. That's what
distorts the fabric.
