Remove the canvases from the wood frame by pulling it off. Make sure there's no canvas stuck to the staples.
Optional step - Remove the staples from the back of the wood frame by using a painter's tool and needle nose plyers. You pull up the staples with the sharp edge of the painter's tool and then pull out the staples with the plyers. I decided to skip this step because it's a bit difficult to do and the paint will hide most of the staples anyway, but if you want a perfect looking lantern, you can do this step.
If there are any rough spots on your wood frames, you can sand them down with sandpaper .
Paint your wood frames and paint sticks.
Once the paint is dry, glue the corners of the wood frames together. Hold together firmly until each frame dries (about a minute). Be generous with the glue because you want it to hold up well.
Add a dab of glue to each end of the paint sticks and put them across the bottom of your lantern. You can add a slight space in between the sticks to give it that shiplap look.
Decorate the inside of the lantern. I used a 6" mini wreath and large pillar candle.
