Adding the three borders to my wall hanging didn't go well.
The seams of the first border puckered. I should've taken the time to find out why, but I continued to sew them on instead. I was hoping to literally iron them out, I guess. ;-))
Anyway, prior to this project all I had done with the Singer 127K was a couple of test runs after I had oiled it. In other words, this was its first real project.
I had to tinker a bit with the stitch length when I started the paper foundation piecing, but the tension was fine. And remained fine most of the time.
But this is what I couldn't figure out: occasionally the tension setting changed apparently, particularly when I hadn't used the machine for a couple of hours. And then I would have to find the correct setting again first and continue to sew.
Now, I'm a beginner when it comes to hand crank machines. I'm not sure how they're supposed to behave. My first sewing machine was an electric Singer 191B. I still have it, by the way.
As I recall I hardly ever had to adjust the tension on it. It would sew anything.
Anyway, after trying every setting of the upper tension I resorted to adjusting the screw on the shuttle by turning it 1/8" anticlockwise. As a result of that the seams of the last border strips were fine.
Of course I still need to unpick all the borders, and start over. Hopefully the tension won't give me any more problems this time around. However, if the tension problems keep reoccurring I obviously haven't solved the problem. I feel I need a professional to have a look at it.
But first I'm going to start over with the borders, and see how it'll play out.
Time to show and tell, so here's some more pictures I took. Come to think of it, maybe it wasn't just the tension issues. After I added the first border I removed the paper foundation. Some parts of the houses stretched a bit. I chalked it down to how the pieces were cut. I hadn't paid any attention to the grain. After all, the paper foundation acts as a stabiliser. Maybe I should've left it in.
