How to Sew a French Seam | Sewing Machine


Hi, I’m Jennifer from Workroom Social, and
today I’m going to show you how to make a French seam. We have our two pieces of fabric here that
we want to sew together, and we want to sew this with a French seam. To get a good idea of what that would look
like, we should identify a wrong side of the fabric. Here we have our two wrong sides. Now, this is one of the few things that you
will sew with wrong sides together. So you want to take your two X’s and match
them up, and then you are going to sew a narrow seam allowance. We are going to sew about a quarter of an
inch. I’m just lining up my fabric with the outside
of my presser foot, and that’s about a quarter of an inch, and then you’re just going to
sew a straight stitch, and I’m on a 2.5 mm stitch length. Then after you sew the wrong sides together,
you want to press this seam flat. You don’t need to iron it, but if you just
finger press this to get the seam to open a little bit, then that helps this side lie
a little bit flatter. Now what we’re going to do is we’re going
to take some scissors and we’re going to trim away about an eighth of an inch from the seam
allowance, so we’re cutting the seam allowance in half. Now is the time that we’re going to sew right
sides together. So with our right sides facing us, we’re going
to lay right sides together, and we are going to do our best to push out this seam so it’s
nice and flat. Grab some pins. You can pin it in place to hold it. We have our seam all pinned into place, so
now it’s time to sew. Before we do that though, you should think
about your seam allowance, so I’m going to do my total seam allowance is 5/8th of an
inch, which is a very common seam allowance, and we sewed the first narrow seam at a quarter
of an inch, so 5/8ths minus a quarter is 3/8ths, so to get the total 5/8ths, right now I need
to take this back to the sewing machine, and sew a 3/8ths seam allowance. I’m going to line up my fabric with that 3/8ths
marker that is on my seam guide, and I’m just going to sew a straight stitch following that
guide. Then when you’re done, you can take this to
the ironing board, and you’re going to press your seam to one side because they can’t open
anymore. Our french seam encloses the raw edge within
this bit. This is the right side of our fabric, and
then this is the wrong side of our fabric with our French seam.
