My wife got into a daily design challenge in March 2016, and she's been doing design practices every week day for the past 4 years.
I helped her set up this website to share her work and maybe generate some revenue if all goes well.

She uploaded the first 600 designs, currently at day 1059. Hoping to catch up with all the uploads for the official launch.
I’ll get back with some stats and numbers about this soft launch if you’re interested.
