Go to Walmart or Michaels for supplies you can look at and choose what works for you.
On large projects you can use a big hoop or move a small one around. You will find lots of accessories everything from stretcher bars to stands, but all you really need are the right fabric, some thread, a needle, for many a good hoop and a whole lot of patience. Good eyes are always a plus. Enjoy yourself, now you've got me wanting to pick up a project. I've used stretcher bars (cheap, snap together wooden frames) in the past on big projects.
