While there's certainly nothing wrong with being a sports fan, sports-themed linens might not be best item for your wedding registry, and here's why: First of all, for the most part, these linens usually look and are pretty cheap, and many guests don't want to buy a cheap wedding gift. Secondly, sports-team bedding doesn't exactly scream "romance," either. Thirdly, your gift registry is supposed to include practical items that you really need. What if you wind up with one set of sheets, and it's the one with tiny footballs on it? You'll regret not registering for the plain, white, practical sheets you now desperately need.
