For a “yellow” swap on swap-bot.com:

I hope she thinks there is enough yellow in it to count as a yellow swap. It is much brighter yellow in person.

I used Baohong hot press paper, QoR watercolors, uniball Air micro pen

(edit: I attached it to a watercolor card and put a bright yellow envelope with it. Very pretty, and definitely yellow-themed! The intended recipient likes flamingoes, so I think she will enjoy using it!)
