Like @Maplestock pointed out, I agree that scrapbooking and writing are intertwined (for the most part - there are some people who scrapbook without journaling just for the creative process). However, I don't think I would identify myself as a writer.... but I also find the journaling or 'storytelling' part of scrapbooking to be my weak spot. At the same time... the reason I scrapbook is to tell stories and to have a written record of things. So it's a bit of a conflict, haha! I often find that I have a hard time expressing what I want to tell, and how I feel. (For example, I've probably edited this post about 6 times already, because I don't feel like I am expressing what I mean properly ) I feel like a lot of my journaling is facts sometimes... who, what, where, when. Which is good to know, but I also want it to be more story and feelings than just the basic facts. I've been trying to incorporate that into my journaling lately. As with anything... I think it is just the practice of writing that will make it better.
Last year I took Ali Edwards "31 More Things" class and thought that it helped me, and I really enjoyed it. (Sidenote - I think that class is on sale, or part of a bundle on Ali's site right now...?) As most scrappy people know, Ali's so great at the storytelling aspect of scrapbooking, so I've found taking her classes and subbing to her kits and having the classroom content that is included so helpful in pushing me to tell more stories vs. facts.
