You don’t have to be a Rockefeller to build a city. Build Your Own Chicago flat-packs paper versions of Chicago icons, $1.50 or 25 for $36. These mini streetscapes are perfect for artful arrangements on bare mantles or bookshelves and could come in handy for those servants of the Second City particularly prone to homesickness. Iâ€™ll be ordering a mini Wrigley Field to slip into my carry-on for long trips. If you’re unsure of your paper-building skills, there are a few free models online for practice. –Katie D.
