Do you own any Cathy Z books? If so, do you like them? Are they for digital scrappers, as well as paper scrappers? The two on amazon have good reviews but I don't know how much they apply to digital scrapping.
They would both apply to digital scrapper entirely. Cathy Z's books are not at all about technique - they are about graphic design principles, font choices and use, etc. All topics that apply to digital as well as paper pages.
I would say Cathy's idea books were the best scrapping books I bought. I learned so much about design and about her great scrapping philosophy! I think these are must haves. I agree with Emmy, the info does apply very well to digital scrapbooking.
