Read the manual. If they offer classes take them as they are a great bonus. Ask what thread they recommend and if none buy just a couple of spools of ones on sale like at Jo-Anns or your LQS. If you are just learning, make your samples all the same size (that is like blocks for a quilt) then you can put them together for a sampler quilt with your new hobby. Remember sometimes it takes a while to have the best results but just read things from here and go have fun. A pair of small scissors for trimming threads is really handy.
