Welcome from Southern CA. Hope you will find as much inspiration as I do from this site.
Might suggest you go down to your LQS and ask for advice. Making a King size quilt is very difficult for a beginner. I know this because I did the same thing in the mid 80s. Try doing some smaller projects first to get your basic skills developed. Quilting is like any other craft such as knitting or painting, you have to develop skills especially with cutting accurate pieces and sewing an accurate 1/4" seam. If you have had some sewing experience, you will pick up the skills quicker. Good Luck!!
