Hello,
We've recently bought a Bernette B79 to replace a troublesome Brother sewing machine, that my mother bought in 1962. The Bernette is an amazing machine, so easy to use, and it sews beautifully. Sewing machine technology really has come a long way since the 1960's.
We were very keen to try out the embroidery mode, so we followed the instructions and fitted the embroidery module. Then swapped in the high-tension bobbin case, the embroidery sole plate, the embroidery foot and the embroidery needle. But we didn't have any embroidery thread, so we just used regular sewing thread, and we didn't have any stabilizer backing fabric so we just put an old T-shirt into the hoop. We created a design, just a 5 letter word and started the machine just to see how it would come out.
But unfortunately it didn't go as expected. I'm hoping somebody can explain to me what went wrong.
It embroidered the design, but it was almost entirely in the white bobbin thread, not the red top thread. Which I guess means the tension isn't right? Or the embroidery needle only works with embroidery thread? Or the high-tension bobbin case only works with embroidery bobbin thread? Or the fabric was too thin and stretchy?
Then it got worse, on the 4th letter, BANG! the needle slammed into the sole plate and broke. I replaced the needle and restarted it. After a few switches it did exactly the same thing again.
I guess the next step is to try again but do everything properly this time. Embroidery thread on top, embroidery bobbin thread underneath, and stabilizer backing on the fabric.
Any advice welcome.
