Nothing new. If you're unsure about a sewing or crafting book and amazon doesn't provide any reviews or enough reviews, feedback, etc., go to your local library and check it out. I do this all of the time.
I even renew and if it's on the last renewal, I'll see if it's on a wait or hold list and if not, I'll get it again!
That way, if the book/DVD isn't a fit or doesn't flow for me, I can return in and I haven't wasted any money.
