Do you like the look of clusters but just aren't sure how to do them? I was a little intimidated by them last year when I was just starting to scrap. But I've had great luck with templates to tiptoe into creating clusters on my layouts. Mega Clusters, Vol. 1 by Memory Clips would be just perfect to try out some clusters.
Brownie Scraps has a ton of challenges going on at all experience levels. I love challenges because they always make me stretch my skills just a little further. There's something to be learned even doing the Level 1 challenges at Brownie Scraps! Ramona's Level 1 - Challenge Two includes tutorials on using templates in Photoshop or in Pixlr just to get you started!
