Hello and Welcome!
People made beautiful ( and not so beautiful) quilts way back when with only fabric, scissors, needle, and thread. And probably a pattern and marking tool.
i think that the space you have available - and funds - will be determing factors for what you get.
Some of us have become addicts of sorts - buying too much fabric, collecting many sewing machines,, buying every new gadget and tool that we hear of, buying patterns and books we never get around to using -
But this is coming from an 84 year old person that just moved three years ago and was down-sized a lot.
All my sewing machines are from 1960 to about 1985. The only thing I really wish I had - that I don't- is the applique/buttonhole stitch.
Using a suitable needle makes a big difference.
if you can, it is informative to go to sewing expos and quilting shows that have vendors. Its fun to see a lot of things at one time.
