This is a simple project inspired from another Goodwill find. Look for an old shelf like this one. You can either paint it or leave it as is. Then pick up some inexpensive bowls or glasses at Goodwill to use as miniature containers. You can look for something that matches like I did here or you can mix and match. If you do mix and match, different colors and shapes of teacups would be a great way to do this.
Fill up your containers with soil and plants. I used portulaca here. Other great options would be impatients if you’re growing in the shade or succulents if it’ll be in the sun or you might forget to water sometimes. Hang securely with screws or nails. Be sure to water.
