10th Bday Month Tales: Post Pandemic Classes & The Future

THIS IS THE LAST ONE OF THESE POSTS FOR TEN MORE YEARS, WE PROMISE! Gather ‘round now while we tell some tales of times past. April 2025 is our 10th birthday month, so we’re going to reminisce with a chronology of grainy photos and stories that are at least 90% true. 🎉

10th Bday Month Tale #7: Did you know that classes at the tool library weren’t really much of a thing until after the pandemic? 

After the pandemic let up y’all REALLY wanted to get out of your homes. Thanks to you and our fantastic teachers, we went from 0 classes to running a woodworking, metalworking, home renovation, or art class just about every day over the course of a year. We’ve tried all sorts of classes in our little space since then from knitting to blacksmithing with varying degrees of success, and we’re still trying out new ones all the time. BTW - You should totally take a class!



10th Bday Month Tale #8: Did you know that today people check out 12,000+ tools per year, offer 500+ classes per year, and have 1000+ hours of people building their own projects in our community workshop per year? 

We’ve come a long way since we were just a couple hundred tools in the back of the shop, and these stats keep growing! Rumor has it we’re even looking for a bigger space. Pick up a DTL 10 Year Anniversary “Against All Odds” shirt next time you’re at the shop, and thanks to folks like you for making the “cool concept” of the Denver Tool Library a rad reality! 

What are your hopes and dreams for the DTL going forward? What would you like to see happen in the next 10 years of DTL?

10th Bday Month Tales: Workshop Opens & Then a Pandemic

Gather ‘round now while we tell some tales of times past. April 2025 is our 10th birthday month, so we’re going to reminisce with a chronology of grainy photos and stories that are at least 90% true. 🎉

10th Bday Month Tale #5: Did you know the Community Workshop opened in 2018, almost five years after the Tool Library?

Almost five years after the Tool Library opened, it was time to take the leap and get ourselves a front door. We expanded and took over the gallery space up front. We shuffled some things around, bought a bunch of very heavy workshop tools from a weird guy on Craigslist, and started to let people use them for whatever they wanted. It was the beginning of Open Shop, and it was weird lol. Things were much improved once we got our super handy and super helpful Shop Monitors. We also started trying out some of our first classes, like Cutting Boards and Hexagon Shelves w/ Sineah.


10th Bday Month Tale #6: Did you know we opened a drive-thru so people could still borrow tools during the pandemic?

Well, not quite a drive-thru. It was more like some plastic folding tables in front of the door that we called a drive-thru. We’d stack tools on it for people to pick up, and when they dropped them off, we’d spray them down with a lawn pump sprayer full of sanitizer from the city. In the winter the tools would freeze to the tables. In hindsight, we may have over-indulged in sign-making as a coping mechanism, giving the DTL drive-thru its distinct “the end is near” appearance.
