I have a bit of a love-hate relationship with Valentine’s Day crafts. I love the idea of making something by hand—something that feels personal and intentional.
But in reality, Valentine’s Day DIY can slide into overcomplicated (or overly cutesy) territory quickly, which tends to drain the joy out of the process.
