Good idea for reach-in closets! Put up closet rods on the sides if you tend to have access issues. I just did this to my own closet today. I also raised the regular bar by a foot to maximize vertical space!
Last but not the least, don’t forget to enjoy! Halloween only comes once a year and the best way to pull off a costume is to feel good about it and also feel good about yourself. Go out there an spook everyone with your one of a kind Halloween nail art!
