How to Sew a Flat Felled Seam | Sewing Machine


Hi, I’m Jennifer from Workroom Social and
today I’m going to show you how to sew a flat felled seam. A flat felled seam encases the raw edge of
the seam allowance and this is a very common way to finish seams that you see on jeans
and on sportswear. To demonstrate that today, we’re going to
need to identify the wrong side of the fabric. So I’m just going to mark my two wrong sides. I’m going to start by sewing wrong sides together. I’m going to sew a 5/8 of an inch seam allowance. So I’m lining up my fabric with the raw edge
on the 5/8 guide on my seam guide, and I’m just sewing a straight stitch. I’m using a 2.5 millimeter stitch length. I’m just going to go all the way down to the
bottom. Now, so we have our wrong sides together and
our right sides with the seam allowance up. So the next thing I want to do is to just
finger press this seam open, so it lies a little bit flat, a little flatter. Then I want to trim one side of the seam allowance
down short because we’re going to encase it with the other seam allowance. So I’m going to trim this down and leave about
between 1/8 and 1/4 of an inch. Now, to hide all these raw edges, I’m just
going to take this larger seam allowance and fold it under, and then fold the whole thing
over, so everything is hidden. Then you’ll just pin it in place, and then
you can just move up your seam to do the whole thing. Of course, if you’re uncomfortable doing this
by eye, you can get your seam guide out or ruler and measure this fold so that it’s all
nice and even. So we have our seam in place, and then we’re
just going to go to the sewing machine and stitch close to this fold all the way down
to secure our seam. We’ll go back to the sewing machine and I’m
going to lower the presser foot and I’m just going to eyeball close to this edge. Now when you’re doing this, you can always
use the edge of the inside of the presser foot as your guide for an edge stitch. Or my presser foot has little notches on the
right hand side that are also really useful reference guides. Okay, and there we have our flat felled seam,
and this is the right side. This is the wrong side. Of course, depending on your preference, you
can always choose to use this seam look for your right side, if that’s what you would
prefer, and put this one the wrong side. It’s really up to you. But that’s how you sew a flat felled seam.

  1. For a guy who hasn't sewn anything in over 5 years, this simple, step-by-step video took the fear out of doing my current project! Thank you very much for sharing.

  2. I've been doing this seam for a while I just didn't know this is what it was called. Just something I started doing because I thought it would make it a bit stronger (minus the trimming part – I knew there had to be a way to avoid them being so bulky. I'll remember that tomorrow when I am sewing.) This tutorial was still very helpful to show me the best way to do it. Thank you. This may be my favourite type of seam. πŸ™‚

  3. But won't that make the seam visible? Since it's the same view from front and back. I am a new sewer learning from Youtube videos haha.

  4. I noticed that my button down shirts' sleeves also have a flat felled seam . Does one need a special machine to duplicate that look , or can it be done with a domestic machine ???

  5. Sorry if I already asked, but I am trying to make a tote bag with handles, is it possible to make french seams on the side and flat fell seams on the bottom. I know how to make them, but I don't know how to make them "intersect" at the bottom. What and where do I sew first, etc

  6. I really hope I'm wording this right but here goes. I am making a blanket and needed three yards of fabric. The bolt (I think that's what it's called) only had enough for two yards so they ended up giving me what was left on the other bolt which was one yard. So now I have two pieces of fabric, one that is two yards and one that is one yard. How would I go about stitching them together so I'd have three straight yards?

  7. Hi, Joey from Italy here, i recently bought a coat from a Rajesh Pratap store in delhi India and couldn't find a single thread or stitch on the fabric, any idea how he did that or was the entire coat put together by glue?

  8. I thought a true flat felled seam did not have your first line of stitching, then relied on two passes of your second stitch line.This means that when viewed it looks the same both sides and each side has a line of top thread next to the folded edge and a line of lower bobbin thread further in, so you have to test stitch first to make sure thread tension makes matching stitches. Not sure what this stitch is called, but it is a perfectly good stitch, and is easier, so fine unless you are being fussy!

  9. A trick to avoid having to trim one of the seam allowances is to cut your patterns or modify patterns you have so one seam is half the allowance of the other. If you have 1/4” on one and 1/2” on the other and your foot edge is a 1/4” from the needle, you can use the foot edge for the 1/4” allowance and the needle plate 1/2” line for the other one.

  10. What was the white marking pen that was used in the video to mark the x's so easily? I'm looking for a good marking pen/ pencil. Can someone please help me out?

  11. THANKS JENIFER THIS HELPS ALOT LOVE FROM BLOOMIXSONIX78

  12. The sound of this machine makes me cringe. No plastic machines! I way prefer older metal model with there nicer stitch and solidity.
