It has taken me a month or so to post this, but this is one of my favorite recent DIY projects. All you need is an old lamp, a paint sample and a hot glue gun. Admittedly, I was only about 10% sure this project would be successful, which made it even better when it was!
I picked up a paint sample at Lowe's and it is more than enough paint to cover the lamp.
Then, the tricky part, I used my hot glue gun to draw a design all over the lamp. I started pretty complicated here and it takes some practice. Something abstract without straight lines is best as it's practically impossible to get your glue gun to draw straight lines. This has lots of swirls and flowers.
Once you're done covering it with your hot glue, take time with tweezers to remove all of the small strings of glue that probably landed everywhere while you were designing the pattern. If you don't remove them, they get all tangled in your paintbrush and it looks like a mess. So, it's worth it take the time to pick all of them off and then re-paint over the hot glue. I used two coats here.
