Sigh. I feel the same, even though the pine boxes are real good quality, and invite more ideas of painting in colours and even painting pictures on them.
With the cedar, I just want to tung oil them well, really well, so the timber keeps looking good.
Since pine is more easily available, I think I will just adopt colour. And maybe a bit of art on my boxes, and maybe seeing what bees like in terms of colour around their entrance.
I noticed if I wear a pink tshirt, the bees come check me out.
