Besides the embroidery designs that come with your embroidery machine, you can also buy embroidery files or create them yourself. The question is how to get the files onto the embroidery machine. There are several ways to transfer your embroidery files to the embroidery machine. The easiest way is to transfer them to a USB stick and then simply plug it into your embroidery machine.
However, there are also embroidery machines that you need to connect directly to your computer via a cable. If you are using a laptop, this should not be a problem. But if you have a fixed computer, it can get annoying if you have to move your embroidery machine back and forth for every new file. There are also embroidery programs for the PC.
With these you can individualise, extend or combine existing designs and create your own embroidery files. It is best to check beforehand which connections the embroidery machine offers and whether they are compatible with your PC. Especially if you want to work with embroidery software.
There is a large selection of free embroidery templates on the internet.
