In addition to making cute bags, pouches, and clothes, I also sew other things like these below. (The three product images are from Grayflare Inc. website.)
Industrial sewing involves heavier fabrics and larger threads, etc. The best part of it is that I get to use the industrial sewing machine! This is JUKI DU-1181N, and it has sewn a lot of things already. This is a beauty, and it was purchased at A.B. Sewing Machine Repairs. (Amir at A.B. Sewing Machine Repairs is the best! Before I knew him, I took my other sewing machines to the retail shop where I had purchased them for repairs; they were not able to fix the issues on their own sewing machines that they sell and they were not the nicest to say the least.) This JUKI DU-1181N is a very reliable sewing machine and it makes beautiful stitches all the time. When I needed it serviced, it was done in a very timely manner, and I was so grateful.
This 6-feet ruler in the photo below and 4-feet dry-wall square are very useful when I have to mark heavier fabrics for larger products. Instead of a tailor's chalk, I use a mechanical carpenter's pencil in red lead. I also use an electrical rotary cutter for heavier fabrics 0 especially when I have layers of them to cut together. (Scissors wouldn't work because the layers get shifted.) The bolt of heavy fabric can be very heavy for only myself to lift, so it is a two-person job.
Industrial sewing starts at $60 with me - I guess it's a lot of money and you can probably find a better price elsewhere (especially overseas). But it is a lot of work, and I enjoy working for those who find importance in my skills and attention-to-detail attitude.
