Threading and Weaning

The first most important thing in threading and weaning your sewing machine is that you need to have a very good quality thread because if you have low-quality thread then it won’t work well for stitching. So the next basic step is to put the thread on the verticle spool pin, when this is set, the spool caps need to be fixed.

Remember that when you put the spool cap, you should not leave any space as if the gap is there then the thread is going to drop in between there and get tight. Thus, leading to a broken needle, because it gets pulled and snapped. So make sure that this doesn’t happen.

Now for the winding of the Bobbins, take an empty bobbin. Make sure not to mix the plastic bobbins with the metal ones.  This is because they are different from each other and so you cannot mix and match them. For winding the bobbin, you need to follow certain steps.

Focus and follow the little picture and see the criss-cross dotted, then it needs to go underneath and around towards the back and over towards the bobbin winder. Make sure that your thread gets firmly connected underneath, if you get a big fluffy then there is a big mess.

An important and useful tip is that you must have nice tightly wound bobbins for sewing. Next, you will take out your thread inside and out and coming up through from the middle and out to the top. When you follow all the steps thoroughly and accordingly, you can really start well.
