Travelers Notebook Accessories (on a budget!)

Sorry if this isn't the best place to post this, but I just got my first Fauxdori! (Lovely customized vegan notebook off of Cadeneta Notebooks on Etsy)

I'd like to add some accessories that kind of stay in the realm of the rustic/leathery look of the Travelers notebooks (without spending a lot of money! I'm on a tight budget!). I'm interested in a few things including:

-stationary/ planner accessories (sticky notes, paper clips, etc. Everything I'm finding is cute and kawaii and I'd like something more sophisticated.)

-an "organizer" like the tigmod/mod tablet but wayyyy cheaper. Or something that can hold both a Field Notes size notebook and pens (leather or canvas) Are Field Notes notebooks good for sketching in?

-a messenger bag/purse that will fit my fauxfori (leather or canvas) and normal purse items (wallet, keys, makeup, etc.) Something about 10-12" wide. Smaller than a laptop bag but not too small...

-other unique accessories like a wax sealing kit -fauxdori inserts (I'd like a nice watercolor paper sketchbook and maybe something for music composition)

I know this is kind of all over the place and not really specific to this subreddit, but if you can direct me somewhere else to post, or give me some suggestions, I'd really appreciate it! I've looked a lot on Amazon and found some nice cheaper things that I'm considering but I'm not sure if they're great quality. Again, I'm on a tight budget and can't spend like $50-100+ on a single item. I'm looking for budget items :)

Anyways, sorry again if this isn't the best place to post. I appreciate any advice! :)
