DD#2's flute is finally paid in full. She's been paying for this flute for over 3 years (since 4th grade), using her allowance money she gets for doing chores. It's been a long haul and she finally finished it.
To be honest, I thought she'd get part way through the plan and decide she wasn't interested in playing the flute any longer, but she didn't. She faithfully practices and really enjoys it. It was a good investment.
