The scavenger hunt sounds fun! I haven't done that since I was a kid; might be a good excuse to get the family together for an outing.
I enjoy the mindless creativity of painting too - it's nice to just focus on the colours and brushstrokes, almost meditative when you're in the zone. And yes, watercolour especially feels like such a gentle, calming medium -- which is why I love it so much! Acrylics are a lot more bold and fun but in a different way.
I'm also into embroidery these days, though I'm only adept at the backstitch so my designs are rather basic haha. I've been meaning to learn new stitches but haven't gotten around to it. Seems like we all have a creative streak in this thread!
