For your friend who spends too much time on Instagram: A World of Interiors magazine subscription
World of Interiors: $113.02
Instead of that really nice coffee table book you've been thinking of buying, why not gift the magazine that will serve the same purpose 12 times over? Because everyone deserves to have something inspiring arrive in their mailbox each month, and because this is one of the most expensive magazine subscriptions in the world (hence they probably will be reluctant to purchase for themselves), go ahead and gift your friend a year of inspirational, over the top design follies...and then gift a subscription to yourself too.
It's real life print and it will feel incredibly glamorous in the hands of your Tumblr'd out friend.
