Yes, my friend the embroidery business is quite profitable. I have to know some of the folks who just started with small investments and now they are making a huge amount of money every day.The reason is that the embroidery supplies are not that expensive but they are relatively cheap and the only serious investment you require is a decent working embroidery machine.And rest is also important like you should have a good embroidery-making experience that will attract the buyers to buy the designs from you.You should have clear knowledge about your target market because a good business is nothing without proper marketing. You will see nowadays every business or even an individual is marketing their skills or products on social media and other platforms.You can choose to make your services/business website or take a shortcut like just marketing your skills on social media.You should market your product to the desired audience.And last but not the least, be consistent with your work.
