Let me introduce you to sewing machines I use.
The first one is Janome HD-9 v.2. This is a professional sewing machine with only straight stitches (very nice straight stitches). This is perhaps the most used sewing machine in my studio.
Next is Janome Skyline S5. This ones has so many different stitches and functions, and I haven't really explored all of them yet. It is mostly used for making button holes because it makes beautiful button holes of different types.
Below is the first serger (overlocker) Janome 1100X. I use it very often for garment making and many other sewing projects.
I also have a Janome CoverPro 1000 CPX. I must admit I only use this when I hem knit fabric clothes. But I hope to use it for more things with a recent purchase of a new attachment. I have to learn how to use it first, though.
The one below is a basic mechanical sewing machine Janome Schoolmate S-2015. This is a machine made for use in a classroom setting. It's a very solid machine. I use it to teach sewing. It is good to get used to using a basic mechanical sewing machine. This is because once you learn how to use it, the knowledge transfers when you use another sewing machine.
Below is a Singer Prelude (8280). Again, it is a basic mechanical sewing machine to use with a student who is learning how to sew. These basic machines do not overwhelm a new sewist with too much information and too many functions.
Below was purely a joyful acquisition for me a couple of years ago. It's a Singer 15K88 from 1950's. It's a vintage machine, and I took time to clean and oil it, and it works beautifully by hand crank on the side. So, if a power failure lasts for a long time, I can still sew on this sewing machine. This has straight stitches only. She is a beauty, isn't she? I always have a spool of 100% cotton thread on it, and I use it to close shut "fill-it-yourself" tea bags, so that I can compost the entire thing after I'm done steeping the tea.
Another beauty with a pop of colour below is a Singer 338 from 1964 or 1965. It is electric, and it does straight stitches and zigzag stitches. Its power is amazing. So, yes, I do use it regularly. I usually keep a spool of black thread on it, so when I need to sew something with black thread, I just move to this machine and start sewing. It is quite reliable. The motor control is a little bit jumpy, but I used some jumpy sewing machines before, and I can handle her.
The next one is not actually mine, but it belongs to Grayflare Inc. It is an industrial sewing machine JUKI DU-1181N with a walking foot. But I make their products, so I am the main user making Grayflare's laser barriers. This machine makes only straight stitches, and this machine can sew the thickest fabrics that Grayflare chose for their products.
This concludes the tour of the sewing machines I use in my studio and Grayflar's workroom. The truth is I want more different kinds of sewing machines like an industrial chainstitch machine because I want to embroider with it. But that's way too many sewing machines, and I am running out of space.
