Have you ever gone to the store hoping to purchase a birthday candle of a specific number, and of course, the number you're searching for is the only number they don't have in stock?? That happened to me last year as I was preparing for my husband's 29th birthday and could not find a #2 candle anywhere. I then had the idea to just make the numbers out of legos instead, which also saved me several dollars. My son helped me build the two numbers we needed out of legos. And underneath each number, we connected a small tower of about 4-5 square legos which I pushed into the cake to help hold the lego numbers in place. It was a great alternative to buying a cake topper or numbered candles!
