Summer sky and sea letter set

This is a letter set depicting the summer sky and sea. Plume-forming cumulonimbus clouds and a calm blue sea. I felt like drawing waves, so I went to a nearby beach to check them out. Write a message on the cumulonimbus cloud and an address on the beach part of the envelope. Writing a letter while enjoying the summer atmosphere What do you think? ・About letter paper There are no lines. The back of the notepaper is white. ・About envelopes The ocean is printed on a pearlescent envelope.
