I love pencillines and pagemaps! I also check out some of the sketches on the Creating Keepsakes website by Becky Higgins. There are also some on the Scrapbooks Etc. (my favorite magazine too!) website.
there's also the gettin' sketchy blog. They have some really nice one's. There are alot of sites that have sketches. If you google any combination of words like "scrapbook template sketches layout" you will find lots. That's how I found most of the ones I use.
