Building a plaid / pattern designer. Someone I closely know is a much sought-after fabric designer, but tends to use primitive tools. I swear, I've seen them make pictures and catalogues in Excel.

I've never been a web dev, but I've set myself a challenge to make something for them. 2 weeks in, I've got a hacky ugly-ish MVP, but hey - it seems to be doing its job :)
