Holes happen from time to time. Whether your little ones get a little rambunctious and put a hole in the wall or you bump it when moving furniture, there are always times when you have to repair a small hole. Sometimes just moving a picture from one place to the next will leave nail holes that you want repaired.
Adding some colored tigs or driftwood to a mirror would make for a really pretty DIY project! (The best thing is that the website says that this project is 'beginner' skill level, which means it should be more-or-less stress free!)
