Becky Higgins site, as she is the "go to gal" for all things Project Life. I also think her kits are AMAZING! There are several companies out there that offer different kits or Project Life papers. My favorites are Studio Calico (I am FINALLY off of their waiting list), Ali Edwards (great digital files if you are a digital kind of person) and Elle's Studio has some fabulous products, too.
Thanks for stopping by!
