This St. Patrick's Day card features a chartreuse tennis ball at the center, with soft white seam lines that give it a realistic touch. Resting on top is an emerald green leprechaun-style hat with a black band and a small golden buckle, tilted in a friendly, flirty way that feels like a wink shared between teammates. Just beneath the image, “TENNIS” appears in large white letters outlined in black, set on a straight line for a strong, sporty look. Nearby, “Happy St. Patrick’s Day” is written in a flowing, cursive-style line in dark green, adding a gentle, affectionate note to the layout. The background fades from pale lime at the edges into a lighter glow toward the middle, like spring light gathering around the design. A couple small accents in the overall green palette bring a festive touch—💚☘️—without crowding the main image. The hat’s golden buckle sits slightly off-center, catching the eye against the smooth green crown.
