YouTube is loaded with tutorials on everything about quilting! And this blog is also great for help. I find free patterns online also instead of buying books when I don't like all the patterns in them. Plus I like to change the styles of quilts I do. But remember, MY quilts never look like the pattern I started with. And that's OK because they are all original Sunnye's!
Buy fabrics online or at a store ON SALE if at all possible. I buy Christmas fabric in January, for example, to get a good price.
The others have told you about mats, rotary cutter, etc. I started with a Brother machine and now have a Baby Lock but the Brother was fine.
Welcome from KY and good luck. (Don't let the pictures from these wonderful quilters discourage you. Mine don't look as good as theirs but I still like the process of it all.)
