Even more on pressing.
There is a lot to say on this issue and I am sure during my regular 2:45 a.m. wake-ups I will keep remembering more to talk about.
Just pressing seams is huge.
It is entirely possible to ruin your project by pressing mistakes. I should know.
Couple of things.
First of it is important to remember that underneath that seam is a seam allowance. Press a seam flat from the right side and there is a good chance that you will press in ridges representing your seam allowances, on either side of the stitching line. IMO opinion this can make your garment look sort of worn out even before it has been worn.
So what can you do?
First thing is to press from the wrong side. Before you press the seam open, press it as you have sewn it to the side and flat, to impede the stitches, then press that seam open.
From the wrong side.
To avoid the seam ridge thing you can lay some paper strips under the seam allowances, between the seam allowances and the garment to insulate the garment from the bulk.
You can do this with long brown paper strips or envelopes. That's what I use envelopes, but I have to tell you not to use any old ones with writing on them.
I have personally, me, ironed in a return address into some nice silk.
The other way, and probably faster, is to lay the seam over a seam roll and press just along the stitching line. Here is my seam roll:
Because a seam roll is round once you lay your seam on it the seam allowances will be lifted from the garment fabric and won't be pressed into it:
Now of course you can buy a seam roll, they are filled with hardwood sawdust, or you can improvise. I have been using a half done roll of paper towel here in the rv, and have used some of those heavy cardboard rolls they have in fabric store for rolling fabric when I had to at home.
And of course the heavy cardboard or sawdust will amplify the effect of your iron and give you a nice clean press.
