choose an iron that is (comfortable) for you- I have an iron i never use- was EXPENSIVE! because it is so dog-gone heavy-even without water ...i hate that iron
a steam iron has steam holes in the 'face plate' a dry iron has a flat face (no holes) I keep a water bottle on the end of my ironing board to spritz fabric when ever i need a little steam- i hate sputtery-leaky irons---but many people love their steam iron features- only you can decide which way to go-
get one that has heat settings like, silk, poly, wool, cotton, linen---not one that just has cool, medium & hot
and get one that fits (YOUR BUDGET)
you do not have to break the bank - or get a loan for an iron- they range in price from $19.95 on up to $250 or more---decide what you think should be YOUR top price.
I've had wonderful Black & Decker's for under $20 from the hardware store that lasted 5+ years & i loved, I've had $60 irons from Bed Bath & Beyond...that i love...and that really expensive iron which i hate (and keep stashed away in a closet)
read the boxes, think about how YOU use an iron-determine 'steam or no steam'; comfortable weight, stays on or turns off, and price-then get the one that meets your requirements.
