I'm pathological about not buying/gifting people stuff that'll likely end up in landfill. My mother, sister and I had a conversation just before last Christmas about not giving one another anything that wasn't ethically made or sourced, it had to be sustainable, environmentally responsible and carbon-neutral if possible.
There are loads of amazing small-batch makers of everything from candles, cosmetics and bath/body & wellbeing products to pencils, art supplies, pet accessories, food & drink, clothing, jewellery, throws/blankets, home decor items, ceramics/table & kitchenware and everything else you can think of.
A company that could bring together a big range of truly ethical, sustainable & environmentally-conscious products in a 'pick & mix' way, and offering different price points for ready-made gift selections would probably get my business around Christmas time.
There's SO much 'sameness' across the retail board these days that, for me at least, small-batch manufacturers and artisan makers offer an opportunity to send gifts that offer something unique. I also love buying for myself, too, and especially like things such as beeswax candles, flowers, artisan cheese, wine, vodka, blankets, bed linen, soaps, skincare, shampoo, body oils/bath products - all made mainly by UK-based makers/manufacturers.
Lots of people would love to gift in a more ethical way, but may not have the time to spend finding the products - plus, buying from several small suppliers means multiple delivery charges, whereas being able to shop in one place eliminates that.
