Thank you for your helpful replies! I don't know how to change the title of the thread now, otherwise I would.
I do have both a darning foot and a walking foot, but no instructions on how to use them. The walking foot has a metal guide, but can't figure out how to attach it properly, and also what exactly is it for? It seems to just lay on the fabric, but what is it guiding?
Also, do I attach the extra quilting table that came with it or do I not need it?
I was hoping to make wavy lines, sort of like long twigs or leaves if that makes sense.
