I finished Seth’s Valentine’s t-shirt. And I try hard to salvage most of the things I sew even if they don’t go as planned, but Jon’s t-shirt is a definite did not finish project.
It’s just that I’ve noticed that sometimes the thread breaks a little bit in my serged seams in areas of a lot of stress (like the armpit).
Last week when I was pulling my running top over my head, a thread broke in the armpit because I pulled too hard. I was trying to think of all the reasons that the thread would break and one of the things I came up with was that maybe I needed to use a smaller stitch length (I usually use about a 3) so there would be more thread to help make the seams strong.
So for Seth’s t-shirt, I turned the stitch length down to about 1.5. That was a bad idea because it made the seams really thick. And wavy because there was more thread there than my poor seams knew what to do with! But in my defense, they were super strong.
Seth’s t-shirt came out ok, but not great.
For Jon’s t-shirt, I decided that maybe since I had changed to a smaller stitch length that I needed to change the differential feed to compensate for the waves I was getting.
I’ll be honest and say that I knew that the differential feed changes the way the fabric feeds through the feed dogs, but I didn’t really understand how it changes it or what the numbers mean on my differential feed dial.
So I changed the differential feed to a 2 and serged up the seams in Jon’s t-shirt. That did not go too well! The seams were puckery and awful looking.
So I did some googling so I could learn exactly what the differential feed does, and then I understood that since I had it set on 2 I had actually gathered the seams in Jon’s t-shirt. Not what I wanted to do, but it did make some lovely gathers in the sleeve caps 🙂
I wasn’t happy that I ruined his t-shirt. I hate the feeling that I wasted time when projects don’t turn out right! I was so mad that I stomped around and this is what I wrote in my sewing notebook under Jon’s t-shirt entry:
But now I know more about my serger at least. I still don’t know why my seams would pop sometimes, but I think I probably need to do a better job of adjusting my tension (and definitely going back to a longer stitch length!). If anyone knows why my seams would pop, I’d love to hear why.
Now, I’m working on making me some more jeans. I’m working on trying to fix the dreaded leg twist I’ve been getting. I made a muslin last night and I think I know why I’m getting the twist, but until it’s 100% fixed I won’t be sure. If I can’t figure it out, I’ll probably fly into a rage and pull all my hair out or something!
