San Diego used to be a sea of Charger blue on game days. If I had been a fan, you bet I’d have had a blue sparkleball on my front porch. So how about making dad a game day ball in his favorite team colors? Carl Boro’s San Francisco 49ers ball is a great example. He used hard cups and created team stripes by inserting three different light colors from the top of the halves, so the sparkleball hangs horizontally. You can find an amazing array of single color mini-lights online.
