a) I don't iron anything until I am ready to use it
Fabric usually comes out fairly decent from the dryer and if I hand-smooth it right away, it is good enough to put away.
b) don't starch it until you are ready to use it
c) On a regular ironing board- I iron about half the width at one time - the ironed part falls to the floor as it "overflows"
d) then I turn the fabric around and iron the other half.
I usually set the iron down on a nearby stand or on the floor while I move the fabric to maximize the available board space
I usually only iron fabric on the wide part of the board -
if I do use the full length of the ironing board, then I only do about six inches of length at a time before moving the fabric.
