I’ve been working with a young couple who is forced to live with those white walls that many landlords don’t allow you to paint when renting an apartment. I randomly came across an image of a space that used tape to create a cool effect on plain walls. This is perfect for people who want to try something bold but are afraid of the commitment. Don’t like it, just peel it off. Etsy sells a wide array of colors and patterns. They’re inexpensive and they’ll make great stocking stuffers. And if people look at you funny for gifting them tape, just direct them over to this post here.
I say there’s no harm in trying.
You can have a lot of fun with them in kids rooms.
