Thanks Nightowl π Ever since a crafty friend told me about corner to corner crochet in combination with pixel art, a whole world has opened up!
This is the pattern I used for the hummingbird:

The piano pattern, weirdly enough, I can't find anywhere. I printed it ages ago, but never got around to actually using it. believe I went to some free icons site and just blew up the icon till it was large enough to print... honestly I don't remember.
Then crocheted a border around till it was as big as my bench. Then stopped increasing and crocheted a number of rounds in V-stitch to make it fit snugly around the bench. That's all really... Oh wait, I did lace up the last row, so that my moving b*tt doesn't shift it around too much π
I can't wait to see what you come up with for your bench!
