I made a rainbow star block for Tori in Hive 1, using a pretty shade of blue-green.
I made almost the same block for Lanakila in Hive 2. I used the same shade of blue-green, but added a star of the complimentary color red-orange. She also asked for a slightly different size.
I made this modern pinwheel for Andrea in Hive 7 in aqua.
And finally, I couldn't resist this adorable little gnome for Jennifer in Hive 9. I left him a little big so that you could trim him down to the size you need.
