Boy, those shamrocks grow quickly. This one is a cultivar and has a red cross in the middle and, apparently, will have pink flowers.
I could show guitar cases drying, again, but been there, done that.
The other plant most noticeable in the photo is Amaranthus which I grew from seed. Some of the plants are about to get their distinctive chenille-type flower.
As for art, one thing I experimented with is I covered the drips on the side of the guitar with more acrylic drips and glitter. This probably was not a good fix for the drip problem but it'll look good on a wall.
