Let's talk about the themed embellies & pp we use most.

100% theme scrapper here. My sons are adults now so I get specialty theme paper made like with their college name on it, their major, etc. I cut it in strips or blocks and use it on the page.

If there is a 3D sticker for whatever theme I am probably going to use it unless it is too ugly to be rationalized.

I especially like the photo realistic paper if I can find one that will work in my theme. Am working on my England album and used several different sheets of paper with a castle photographed on it, I'm using paper with old bricks and wood and coastal papers.

If I have pictures taken at restaurants I turn to my stash of food and restaurant paper and my ribbon with silverware on it, haha! I showed some of my layouts in grammadee's challenge thread and you can see my need to tell the story with the product I use.

I'm a mix of being a theme and non-theme scrapper.

What I use the most? Christmas & Beach. I love to scrap both of those and usually my photos look great with the themed paper bc they usually coordinate. I.e. we are wearing beachy summery colors at the beach

I could really use some more summer/beach embellishments that aren't flat stickers. Like wood veneers, printed chipboard pieces, etc. As soon as I find good ones, I use them! I'm like grammadee with her Zva embellishments

I love little boy stuff too and use a lot of it with stars, especially.

And I love baby animals on baby pages! Those are mixed in with my zoo stuff too since we go to the zoo a lot!

I'm not 100% theme, but I do a lot of themed pages because I tend to be an event photographer. LOL, Even many of my non-event photos turn into events! 

Christmas, Halloween and Birthday are the categories I probably buy most often, followed closely by vacation/Disney.

Christmas: gingerbread people, trees, lights, ornaments, Santa and reindeer, stockings, baking stuff.

Halloween: Used to be more traditional Halloween stuff, but now with DD being TOTing age many of my photos are of her in her costumes and they are decidedly UN-Halloweeny (Elmo, Elsa, Rainbow Dash) so I end up having to buy cartoon themed things for those pages. I still get pumpkins, Jack O'lanterns, candy, etc. especially the cuter ones.

Birthday: I buy a LOT of pink and purple birthday stuff. A lot! For the two years DD had Mickey parties, I will have to raid my Disney stash to make those pages because there were a lot of primary colors for those parties. This year was My Little Pony, and it kind of surprises me that there isn't more ready made MLP scrapping stuff!

Disney: I don't even know where to begin with this one. Paper with polka dots, especially black, red, yellow, pink. Anything Mickey or Minnie, but we also got tons of character pics with the other characters which meant I bought every giant patterned paper stack pad I could find. I don't tend to like how most of the papers are laid out though. I find them hard to use so I'll probably end up cutting out the characters and using them in different ways. I'm a sucker for packs of embellishments and stickers too, even though I typically don't use them much either. To go along with that, I end up buying tropical vacation type papers and embellishments too. I've been on a few Disney trips and a few Hawaiian trips and once to Mexico and the Caribbean, so I figure eventually I'll use it all. Palm trees, beach/ocean, cruise ships, tikis, tropical drinks, hula girls.

I agree that there needs to be more LAKE beach stuff. We're lake people too and a lot of the beach stuff I find is tropical beach, not lake beach (and there's a big difference). I need more general swimming stuff (not team swimming) such as life jackets, pool toys, goggles, jet skis / water skis, pontoon boats, fire pit / s'mores, fishing boats, fishing stuff (again, lake fishing not ocean fishing), and cabin stuff although our lake cabin isn't all that cabin-y and it isn't in the woods.
