Singer Heavy Duty 4423 Sewing Machine Review

When I first used the SINGER 4423 sewing machine, I found it to have a solid metal frame and a heavy duty rotor which is able to tackle any sewing job I could throw at it. The sewing machine has a drop-in bobbin system and a one step needle threader that saved me time therefore making sewing jobs to be more efficient.

This sewing machine was engineered to last and it is one of the best sewing machines for either a novice or a professional seamstress. A novice can use the machine to practice finally becoming a professional seam stress within no time.

Just like I prefer the old style sewing machines, the SINGER 4423 sewing machine is a non-digital sewing machine with a turn dial stitch selection which makes it easy to use. Thanks to the best engineering, the machine has plenty of stitch options for heirloom, quilt or apparel sewing and finally one fully automatic button hole stitch. The best feature about the machine is that it has an extra high presser foot lifter which allows for more clearance especially when performing sewing jobs with multiple layers or thick fabrics. This is great especially when you are sewing quilts.



The SINGER 4423 HEAVY DUTY sewing machine gives the user freedom to sew all kinds of fabric and other projects. Thanks to the heavy duty motor, the machine will keep on going and will not slow down or jam especially when presented with thick fabrics or a lot of layers.

On the other hand, the extra high presser foot lifter gives the user plenty of room for extra layers and even thicker fabrics. The sewing machine has six essential stitch options, twelve available heirloom stitches, four satin stitches and a single fully auto button hole stitch. All these options allow the user to feel free and create fashion clothing’s, heirloom crafts, linens, quilts and dresses. When using the machine, the sky is the limit.
