Question 1

Will it sew leather?

Accepted Answer

It can sew leather providing one uses the correct needle, presser foot, thread and stitch settings for the weight/thickness of the leather. Singer's website has an accessory brochure (PDF file) that can be downloaded and used as a reference for which needles, feet and settings to use for sewing various types and weights of fabric, leather, vinyl, etc.  If you can't find Singer's website, google "singer accessories."

Question 2

I am new to sewing machines...how do I know what type of needles needed for this sewing machine?

Accepted Answer

The needle for your machine does matter, leather needles for leather, shorter needle for thicker fabrics.  Each needle has two numbers.  What most folks do NOT know is the second number.  It is the hole size .  If you have 20/10 vision and fairly young this number will not matter. However, if you are ancient as we are it makes a HUGE difference.  118 is a perfect hole size for those of us with aging eyes.  Remember that your needle will dull.  If making masks: your sewing through folds, it will dull faster.  We have found that keeping a sharp needle is well worth the price.

Question 3

Will this machine blindstitch 3-4mm thick neoprene for a wetsuit?

Accepted Answer

The Singer model 4452 is a home machine.   The Singer model 4452 presser foot lifts to approximately ½ inch space from the needle plate to the bottom of the presser foot, by lifting presser foot lifter.  The presser foot will stay at this height until the lever is let down.   By pushing the lever further up it will go to a height of approximately 5/8 inch; however, it will not stay at that height if lever is released.  Neoprene fabrics can be anywhere from about 1mm-7mm. The nylon or polyester usually accounts for about 0.2mm so the rest is all about the amount of rubber you have.  1-2mm is usually fine for most home sewing machines to work with. 3mm (approximately 1/8 inch) will depend on the machine, and anything 4mm and above is recommended only for industrial sewing machines.  The amount of presser foot lift may not be the issue, if the layers are too thick, the tension will disengage and will not form a proper stitch.

Question 4
