Yes, Josefa, upcycling is totally on trend. Everyone who goes through life environmentally conscious knows that raw materials don't grow back endlessly and that many things can be reused. And it's also a lot of fun. You can do a lot of it with children too; it stimulates their imagination and they learn right away that you don't always have to throw everything away.
I also like that you sorted the upcycling threads by topic. That way not everything is all mixed up, and you can read the thread that interests you by topic.
I'll just continue a little bit here in this one ... I used to do a lot of crafting, so now I have plenty to draw on. Maybe one or another of you would like to try making it too.
So ... there are also the
envelopes made from calendar pages. I had already described that once in another thread. I've linked it above. So when the year is drawing to a close, always keep an eye out for where you can get large calendars with beautiful designs. They are far too nice for the paper recycling bin. You can use the envelopes to give gift vouchers for this and that.
