This machine is capable of stitching leather so long as the appropriate needle, presser foot, thread, and stitch settings are used in conjunction with the leather’s weight and thickness. On the Singer website, a brochure about accessories is available to download in PDF format. When it comes to sewing different kinds and weights of cloth, leather, vinyl, and other materials, this leaflet can be downloaded and used as a guide to decide the needles, feet, and settings to use for each type of material. If you are experiencing trouble accessing the Singer website, you might want to try searching the internet for “Singer accessories.” Singer Heavy Duty 4452 vs 4432
It appears that the difference between the machines is the stitches that they offer, based on what I have seen online; however, I have not had the opportunity to test or experiment with the H 5532. Both the Singer 4432 and the Singer 5532 include fundamental stitches; however, the Singer 5532 includes several additional stitches. The machine and all of its components, including its accessories, function in the exact same way. The Singer 4432 is, in my opinion, a very high-quality musical instrument. I have no trouble sewing with denim and other tough textiles like leather and corduroy. If you would rather have stitches with more decorative detail, then you should go with this choice rather than the other one. The remaining parts are immutable and cannot be changed in any way.
