Design a captivating hand-drawn watercolor clip art image featuring a family gift niche adorned with birth flowers. Customize the image for a family of six: a January baby (Snowdrop), a May baby (Hawthorn), a July baby (Delphinium), a September baby (Morning Glory), an October baby (Cosmos), and a December baby (Narcissus). Add a gentle watercolor texture to the background, giving the image a vintage and artistic feel.
