They undoubtedly makes me think of the ocean (that specific shade of blue is , mystical but still oh so lovely), not so much the sky but at the same time... blue... so yeah, sky as well, especially in combination with the white. The shape makes me think of either spires / scepters, or maybe someone carrying something and the bead in the bottom brings my thoughts to eyes and sight. It also makes me think of swings.
They're very tranquil, and invokes a feeling of peace and calm, making me smile faintly. An almost nostalgic feeling.
