I use steam all the time, but only by using the "button" on the iron, so just give it a shot when and where I need it. I'm not moving the iron, so not distorting anything. I almost never set the iron on continuous steam. Also, I will use Best Press, sizing (my personal favorite) or starch freely.

I find that you can over-press. Often I use the fingernail or an angled wooden stick to press the block pieced during assembly. I press with the iron once the block is complete and I have great success with that method.

Instead of steam, I use a bottle of water in a spray bottle which sits close by to give the block, fabric, etc. a light misting before pressing. I like this better than dry iron or steam iron.

Thanks everyone. I ended up giving my blocks one last press before laying out and assembly but made sure it was just a press and no ironing! Thanks for all the advice...most appreciated and absorbed!!!!

Using starch, how much or how little is personal preference. However, I find I have better results when piecing to use steam in my iron, probably because my starch is "in a safe place"; but Eleanor Burns admits to using steam, so if it's good enough for her, then...

It never ceases to amaze me, how often there are as many answers as there are responses in a thread. Clearly there isn't a "right" answer, just preferences for what works right for you.

I must say that this forum has me quite taken back by how helpful posters are......so many responses to queries and so many different opinions and ideas......this Quilting Board holds a wealth of information and people keen to help and encourage. It is a delight to feel part of it. And whilst I am nattering on here I might also add that it is lovely to read posters being so polite and not jumping onto other peoples threads and diverting topics.:)
