It’s still a work in progress but I’ve made a picture frame holder. This is the 3rd iteration (the first one was an epic fail, and the second one had just a minor flaw).
The slots are just a touch wobbly and I need to decrease the height and increase the length at the bottom, but I’m pretty pleased with it. Never thought I could build anything - I know this is as simple as it gets but I had full-on doubt that I could even do something like this. Now that that’s no longer the case look out LOL!
