Both flatbed and edge banding machine can be used. This brand, Jack's, is better. Brand-new two sets can be made within 8000, and the second-hand ones are much cheaper. If you produce it yourself and then sell it, I suggest you give it up. Because the cost will be much higher than the ready-made clothes you batch outside. I am engaged in garment production and processing, and have my own wholesale stalls and factories. For example, mass production of general T-shirts only needs 10 yuan. But if you process it yourself, there will be great waste of cloth, accessories and labor. If you take the boutique route, you can also try. Many designers abroad do this. Gradually form your own system. I hope it works for you.
