I am just a self-taught quilter. I've only done hand piecing and quilting. I do have some placemats machine pieced, but not sandwiched yet, so that I can try quilting them on my old Viking 940 machine that I love. (I want to do more machine work, so much quicker.) I see all the references on this site to long-arm quilting machines, medium arms, etc. I honestly do not know one from the other, and want to know. So, I'm just gonna show my ignorance and ask! Are these regular sewing machines, or if not, how do they differ from regular machines? Are they all stand-alone units, or do they require the big quilting frames? Are there quilting machines that just do it all automatically? I know, I know ... I told you I was ignorant about them! LOL Enquiring minds want to know!!! Teach me, please!
