I have been terrified of clusters since I started scrapping in March 2020, but slowly Em at TNP and her wonderful gals have been helping me be brave enough to give it a whirl and I am getting better.
I like templates with 'cluster templates' so I can use those as a starting point.
This one by Lorie (LJS) is my fave, I use it a lot.
Here is one of my layouts for TNP, that has helped me conquer my fear and I am learning clusters don't just have to be flowers.
