this is what you will get with the machine, in addition you will embroidery threads if you haven't already got any. You can buy boxed sets of Brother thread to get you started
this shows the accessories that are available for the machine. The stabaliser that comes with the machine is iron on so you may want to consider different types.
this is were i get mine from.
You get 2 hoops the 4x4 and 12x8 so you might want to consider different sizes depending on what you want to do.
Plus the machine weighs 15k so you will need a table/desk that will take that weight, Ikea is a good source.
I have the 10 reel thread organiser
https://sewingcraft.brother.eu/en/accessories/sewing-machine-accessories/ts5this. Although to be honest i only put the thread on the stand in the order i need it and then transfer it to the machine to thread, it is a bit of a fiddle threading it via the stand. Plus if you are going to use the extra large reels of embroidery thread you will need one of
these.
I also have an acoustic mat under the machine as my sewing room has a laminate floor and and it can seem noisy if you are in the room below.
thisDONT BUY THE BLACK ANTI SCRATCH PAD TO PROTECT THE MACHINE, it is a waste of money and after only using the machine twice the hoop got caught under the mat and bent it out of shape and prevented the embroidery for stitching properly.
I only use mine for embroidery, i found the sewing function a bit faffy compared to my Pfaff, but i suppose it is what you get used to.
Hope this helps
