Scrapbook themes, or lack of...

I hear you. There were a couple less vintage sides in the Carta Bella Home Run collection papers (still on scrapbook.com) - I liked the navy. But yeah, not so much the vintage elements. www.scrapbook.com/store/cbp-cbhr313011.html

I'm not a theme scrapper so don't buy specific-themed supplies to scrap a subject. Luckily, the sports balls you're seeking - baseball, tennis, & bowling - can be achieved using tools you may already have, such as circle punches, markers, &/or cut files (if applicable). Adding patterned papers, stencils, embossing folders, punches, stamps, &/or dies on hand in related patterns would also give a nod to the theme (e.g. herringbone, stripes, pennants, squares/diamonds = baseball; grids/net = tennis).  

Note you may already have these sports icons on cut apart papers/sticker sheets/ephemera/chipboard/stamps from boy, play, school, fun/games themed collections (e.g. bowling balls/pins are throughout the Simple Stories - Family Fun collection). Notice the patterns used in the vintage &/or out of stock baseball collections; you may also find the same or similiar patterned papers in your existing inventory.

Consider purchasing a multi-sport stamp (e.g. Pretty Pink Posh - Sports), die set (e.g. Spellbinders - Game Day dies), chipboard (e.g. Mintay Chippies - Sport), etc. that would help you tackle sports that unexpectedly come your way now & in the future.

I feel like Photoplay is usually good for small collections of random themes. I don't follow them to know what they have now but it might be worth taking a look.

WARNING: Photoplay sports collections are branded (although rarely listed at online retailers) as Colorplay, which is printed in-house using glossy papers! 

Fortunately, I do have a stash of baseball papers. I'm going to run out of baseball photos before I run out of product. But yeah, I've been collecting it piece by piece over the years, along with football and basketball.

The Carta Bella collection is definitely retro. I've used it on a page but sparingly. A lot of it is a cream base, and that isn't my jam. I liked that layout, except I embroidered baseball stitching on it, which I love, but somehow I must have measured it wonky. Every time I look at it, it annoys me.

I like the Scrapbook Customs paper with the wood, but if I remember right, it is glossy. I haven't used the baseball one from this line yet, but I used the football paper, and I really liked how it looked, despite the gloss. Scrap Your Trip has a lot of baseball stuff, but their paper is glossy, too.

I do have some Paper House stickers. I use them sparingly, because they are photorealistic, but I've been happy with a couple of layouts I did with those.

I agree with PaperAngel though, on this one. Sometimes we have to make the embellishments ourselves.

But yeah, if there is a theme you think you'll need in the future, buy a few papers.

breetheflea I bought a digital pack because of this for baseball. My kids play in the disability league every spring and nothing out spoke to me.

I like PaperAngel ideas as far as balls are circles, start there maybe?

Was there a mascot/team name that you could focus on? Or did you eat some ballpark food? I think for me, attending the game has less to do with actual baseball and more about the other stuff we do as fans.

Also for baseball - I am thinking red stitching or red dashes to represent the stitches on a baseball.

What about font/lettering - like a varsity type font?

Let the photos tell the baseball story, then accent from there maybe?

Any memorabilia (ticket, program, receipt) or could you print a logo from the team website?

I have quite a bit of Graphic 45 Sports related stuff, papers, embellishments and such. Let me know if I can share some with you.

If you cannot find what you need, I'd think in terms of basic baseball colors. So white balls with red stitching and green grass. You can also go with team colors. Also basic shapes like white circles, green diamonds.

Oddly enough, at least for stickers, I like to check out Dollar Tree. They upped their sticker game considerably in the past few years, and have a lot of sports related stickers.
