My botanical gallery wall has been one of the best DIY decor investments I've made over the years. It fills a large space, and with it's classic, timeless appeal I've had it in place for over 5 years now and have never grown tired of it yet. And, coming in with a total price of around $100, it was pretty affordable for the high impact it gives.
Here are a few botanical books with pages suitable for framing if you'd like to create your own botanical wall. There are so many pretty options, I think I could do a different wall in each room! I've linked to each book underneath it's photo. Most of them have a preview of the pages inside if you click on the link.
This is the book that I used for my wall. I did my gallery wall and a slightly smaller one for my sister-in-law, and there are still plenty of pictures left in the book. One thing to note with this book, it has a crazy fluctuation in the price. I paid around $35 for it, it's currently around $70, and I've seen it for as high as $200! I have no idea why that is (if you do I'd love to know!), but if you're interested in it I'd recommend just checking on it frequently and striking when the price is low.
I really want to purchase this next one soon. All of the botanicals are on a black background and the colors are so vibrant!
These selections are in a series with 6 available editions. They unfortunately don't show previews of any of the content pages, but just from the covers I think I'd risk taking a chance on one. Plus, if they've published 6 in the series, they must be good! These as well as the last two books specifically state that the pages are blank on the back so that they are geared more specifically towards selecting the ones you like, removing the pages, and framing them.
How fun would this one be if you live in a warm climate/desert area?
There's more information in the original tutorial post if you want to know about the frames or the assembly process.
