Checking your 1/4″ seam allowance- How do you?

There are many times when I follow all the instructions to a T.  I check the cuts, measurements, sew everything in the order that I was supposed to…but something is off!  The block doesn’t square up.  It is too small, or too big.

Something was wrong.

Come to find out it was my seam allowance.  Yes. Something so small compared to all the other things that can go wrong, yet, it messed a whole bunch of things up…not to mention the cute {and expensive} fabric that I was using!

Checking your 1/4″ Seam allowance-

There is one way to do this.  Sew a straight line.  Place the fabric in your sewing machine and sew like you would normaly.  If you are using the sewing foot guide, or a mark, or whatever  it is that’s fine.  Just sew a line for now.

Take a ruler and measure from the edge to the stitch line.  Where are you at?  Are you right on the 1/4″?  Under it? Larger?  Figure this all out before you start making adjustments.

If you are off in either direction-larger or smaller, you will need to make some adjustments.

Here are a couple of ideas on how to adjust your 1/4″ seam and how to sew it once you found the sweet spot:

  • Can the needle move position? Sometimes a simple adjustment can do the trick.  My machine doesn’t have the option of needle adjustment, so this doesn’t work for me.
  • Use a seam guide.  I measured though and found that I can’t have the edge bump right next to the sewing foot.  It has to be just inside of it to give me the 1/4″ measurement.

  • Mark either with tape or marker where your fabric edge should like up on the machine to get that stitch in the right place.

Notice that I am not using the 1/4″ seam foot.  If you don’t have one {you should totally run out and buy one right now} you can use your regular foot.  Mark with marker the spot on the foot itself or use the tape as a guide.

The problem with the tape –for my machine– is that I have a drawer.  So, everytime I get in there I have to remove part of the tape and then it isn’t as correct as when I put it there in the first place.  Something to think about.

    The only comment that I have is to remember that everyone has their own “personal” 1/4 inch. it really doesn’t matter if your seams are exactly 1/4 inch wide. What matters is that your seams are consistently the SAME SIZE.

    Some of us use a scant 1/4 inch, simply because that’s what is easiest to measure on my machine.

    My machine also has a drawer. So I placed the tape correctly, then with a razor blade I carefully cut the tape at the split where the drawer will open, leaving the tape still on the machine. That way the tape stays secured and I can still open the drawer.

    I check my seams every now and then, because if you hit a pin (which you’re not suppose to sew over) it can adjust the needle alignment. I use a 1/4″ foot and love it. The tape also gets in the way of bobbins. I have used a permanent marker on my other machine.

    I simply use my ruler and draw a faint line with a pencil. Can’t go wrong!
