I've been quilting for quite a few years. Until recently I was unaware of the practice of setting the seam with your iron before you press the seam to one side.

I don't know why we are supposed to do it, but I am convinced that I am having more luck with accuracy since I started setting my seams.

Anyone know the rationale to setting the seam?

I am not sure why it works, but I agree that it does. I also tend to press my fabrics when I align them to sew them together. It helps to prevent shifting. I believe it holds better than pins, unless I have to align seams.

I didn't know about this until recently either; sure does make a difference. And I was pressing seams from the back because I thought it would work better...who knew? (Well apparently a lot of people knew, just not me!) :lol:

The rationale is that it helps sink the thread into the fabric, instead of just sitting on top.

Can someone please explain how you set the seams?

Press the seam while it is still closed, then press it open. I also have started starching my seams when I press them open. It seems to make them lay flatter.

Thank you!!

I "set" my seams now and find it really does make a difference a teacher at a course told us to do this many years ago she said you need to "sink the thread" to press sharper seams.I couldn't see the point of extra work then but now I do!She was a remarkable teacher and taught us so much.

I set and use a tailor's clapper to make the seam flat. You won't know the difference until you use one. I also use the Steady Betty. My blocks are perfectly flat and the cut fabric pieces are never distorted by pressing. Little details make a big difference.

I was wondering the samething. I'm glad you finally asked.
