My budget is under 800 so the collar is using webbing (about .6inches thick, fabric and minky not sure if of the exact thickness. I would like to use a thicker thread but my machine now can’t take a thicker thread also the photo is not my work but a picture of what I’m going for. I’m using a BERNINA activa 230. Not sure what needle but I went to a local quilting store and she gave me a better needle to try to go through everything.

Hello I am new to sewing. I’m not technically using leather yet but I sew dog collars that are very thick made of webbing, fabric, and minky and eventually I would like to use leather. But I’m looking for an affordable used machine but have no clue what to look for on Facebook marketplace does anyone have recommendations for ones most often found used online?
