Read all you can and go to places where quilts are shown and examine them carefully. If possible find a group you can join. Quilters are sharing people. At least I find them to be that. Read books (library's usually carry a selection of quilt books-or inter-library loan, can get almost any quilt book you want to see.
Then practice, start out with some fairly easy blocks and work your way up. Take classes if there are some in your area. Or purchase some of the video tapes that are out there now. Then be kind to yourself. Don't expect perfection in the first quilt you make, goodness I've quilted for over 40 years and still mess up. Make a wrong cut, or sew a seam that isn't accurate.
Get the best machine you can afford and keep it oiled and cleaned. Then just enjoy the process.
