Brother BB370 vs. Brother ST531HD Comparison

You’ve landed on the right spot if you are trying to compare Brother BB370 and Brother ST531HD. Which one is right for you? Their excellent quality makes them a fantastic choice for anyone who enjoys sewing.

What are the major differences between them? Here I will try to answer them as simply as possible.

Brother BB370 vs. Brother ST531HD: Comparison in Features

Sewing Machine Types

Both Brother BB370 and Brother ST531HD are mechanical sewing machines. Although a mechanical sewing machine has fewer stitch options than a computerized one, they are easier to maintain and cost less.

Brother BB370 vs. Brother ST531HD : Built-in Stitches

The Brother BB370 sewing machine comes with an attractive amount of built-in stitches, 37 to be exact. Within those 37 stitches you can find standard stitches, decorative stitches and easy-to-use buttonhole stitches. While the Brother ST531HD features 53 stitches. Similar to the Brother BB370, these stitches include standard and decorative stitches.

Start/Stop Button

Neither Brother BB370 sewing machine nor Brother ST531HD sewing machine has a start/stop button. This might not be convenient for a novice to sew effectively.

Speed Control Slider

Neither Brother BB370 nor Brother ST531HD sewing machine has a speed control slider. With a speed control slider, the sewing speed will never go above your selected speed, no matter how hard you press on the pedal.

Automatic Needle Threader

Many sewing machines sold today come with an automatic threader function. This is essentially a lever that will guide the thread through the eye of your sewing needle for you so that you don’t have to do it yourself. Many sewists prefer to thread their own needles, but if you have difficulty performing this task, then a machine with an automatic needle threader might be very useful for you. Fortunately, these two sewing machines both come with automatic needle threader, allowing you to thread the machine with ease.

Drop-in Bobbin

The advantage of easy drop-in, top load bobbins is that you can readily see how much thread is left on the bobbin through the window. You do not have to remove the bobbin case to insert a new bobbin, and you do not have to remove the accessory tray from the free arm to change bobbins. Both the Brother BB370 sewing machine and the Brother ST531HD come with this user-friendly feature.

Programmable Needle Up/Down

With a programmable needle up/down function, the needle will stop down in the fabric, allowing you to raise the presser foot and adjust the fabric without the fabric moving out of position because the needle will hold the fabric in place. However, unfortunately, these two sewing machines come with this feature.

Free Arm

There is free arm on both the Brother BB370 and the Brother ST531HD. The free arm is a very useful feature to all sewing machines as it makes sewing one layer of fabric without catching another. This is because all of the workings around the bobbin race, feed dogs, and needles are housed there.

The Verdict

Feature-wise, the Brother BB370 and the Brother ST531HD differ a lot. However, the common factor is the stitch quality. These two machines provide consistent stitches over a variety of fabrics. If you ask me to pick an affordable advanced sewing machine, I will pick any one of these two machines. Since they differ a lot in features, I won’t make a suggestion. The decision has to be made on your sewing skill and sewing level.

Q. How do I thread a sewing machine?

To get started with your sewing project, you’ll need to first thread your sewing machine. While your machine’s manual should guide you in the specific sequence for your make and model, the basic process starts by placing the presser foot in the up position.

Next, put your thread spool on the spool holder and bring the thread across the top of the machine, through the thread guide. Insert the thread through the tension mechanism, sliding it between the metal disks before pulling it back upwards. Find the take-up lever and place the thread into the hole. Pull the thread towards the sewing machine needle, using available thread guides as you go.

Finally, bring the needle into an accessible position by adjusting the handwheel. Insert the thread. Your sewing machine should be threaded and ready to go, but it’s always a good idea to make a test run on a sample swatch to check your work.

However, if you sewing machine comes with an automatic needle threader, that would save you lots of time.

Q. Can i use 3 in 1 oil on my sewing machine

A. You shouldn’t use cooking oil or automotive oil in your machine, since doing so may clog the gears and damage any fabric used in the machine. Also, 3-in-1 oil is not suitable for sewing machines, according to Threads magazine.

Q. Can a normal sewing machine sew canvas?

A. Yes, canvas can be sewn on a regular sewing machine.

Q. Can i use clipper oil on my sewing machine

A. Yes, you can as some people do recommend it as an alternative to sewing machine oil.

Q. What should I know about manual vs. electric sewing machines?

A. Manual sewing machines were the mainstay of the crafting world, but in more recent years electric (also known as computerized) machines have been increasing in popularity for their easy operation and advanced functions, such as embroidery.

If you’re looking for a simple sewing experience without frills, a mechanical machine gives you straightforward functionality.

Without electronic components, some feel that these machines prove more reliable in the long term.

However, computerized machines may shorten the learning curve for some new sewers, since choosing stitches and settings only requires the push of a button.

Q. Can I interchange metal and plastic bobbins if they are the same size?

A. Metal bobbins and plastic bobbins of the same size can NOT be swapped. Machines are set for a very precise tension setting. If they are set for a lighter plastic bobbin, the tension will change if a heavier metal bobbin is used.
