I guess crafting is the most expensive one. I'm not a person with a massive stash, I actually wear the clothes I make, and crafts that look expensive can turn out to be a really cost- effective, like a €50 embroidery kit that takes 200 hours to stitch. What makes it expensive for me is that I take a lot of classes, most for sewing and pattern drafting but some others as well. I pay €€€ to learn from the best because the others don't have much left to teach me after 25 years. At an average cost of €90/month crafting is my biggest expense after mortgage/bills/food/health insurance.
