Hi M.!
Are you making books for each child? That is what I do. When I work on my scrapbooks, I work on 30 pages for one, then switch. 30 pages sounds like alot, but the way that I get it done is laying out my pages before I actually scrap them. I use a Power Layout system from Creative Memories. I get my BIG stack of pics and place them on a plastic 12X12 planning sleeve (this comes in the Power Layout Box). I try to put alot of pics per page b/c I want to maximize my space. After I lay the pictures on the 30 sleeves, I move to paper. I have my paper from CM and Hobby Lobby oraganized in 12X12 sleeves by color and style. I go to my paper and just start laying paper that coordinates with my pictures. At that time if I have a brillant idea for that page, I write the idea on a post-it and place it on the plastic sleeve along with any necessary paper. For example, I have a layout of the kids climbing trees. So I decided that I would make a tree. I got the necesary paper to make a trunk and leaves for that page. After the paper, I go to my stickers and cut out or place stickers that I may use on the page. Then I stack my 30 pages in my Power Layout Box and put it away for another night or occassion when I can work. I normally do this organization process in one evening. It really does not take long. On a different evening, I get my box out and my tools and go to town! Scrapbooking this way is fast! So, if you are looking to get LOTS done, this may be an option for you.
As far as stickers, paper, etc. I would suggest laying out your pages with your pictures, then making a list of the paper and stickers that you "think" you may need for each page. I do this too when I am laying out my pages and don't have a sticker or just that right piece of paper.
Another alternative is a ready make package of stickers, paper, and an idea book. Creative Memories has these too! They are called Power Palettes. They are really great time-savers, but are not extremely decorative.
Good luck! If you have any questions, feel free to e-mail me back. I also have a website with great tools and ideas that you can shop or just get ideas! Check out www.mycmsite.com/beckywalker
