There's something to be said for taking a beginner series on quilting from a regular quilt shop. It might cost more than a quick class at Joanns, but you get what you pay for. The shops near me all seem to have some kind of "Quilting 101" that walks you through everything from accurate cutting with a rotary cutter to reading patterns to piecing to finishing. I've seen too many people who get frustrated because their quilts don't look as nice as the picture on the pattern because they overlook things like consistent 1/4 seams or cutting on the straight of grain.
