The pattern itself looks doable for a confident beginner. But I have to agree, the price is pretty steep. You'll spend over $377, and that doesn't include backing fabric or batting. But if it's you're first foray into quilting and you feel more comfortable with the fabrics being supplied for you, then this is certainly a good way to go if money isn't an issue.
Good luck and keep us posted on your progress! :-D :-D
