Almost every evening, I light my recycling candle - it has a permanent glass fiber wick and is fed with scraps of wax and candle leftovers. (Here is the link to the manufacturer.)
The soap foam pump is another one of my favourites: with only a very small amount of any liquid soap - and a lot of water from your cold water-tap - it produces soft soap foam, nice to your skin, nice to the environment and nice to your wallet.
Two months ago I stumbled upon this link and this other link and decided to try out sewing and wearing my own fabric panty liners. I admit I was a bit sceptical at first, but now - after several weeks of use - I sure am a believer: wonderful to wear, easy to sew, and a very good, sustainable alternative to the disposables ones.
(If you don't want to sew yourself, there are several sellers at Etsy who'll do the job for you - here's the link.)
While recycling your old flannel sheets and shirts for the panty liners, you can use the fabric scraps for making your own cotton rounds as well - when used, I simply throw them in a small laundry bag hanging in a corner of the bathroom, and wash them together with the towel and bed linen laundry.
(Of course there are sellers for these things too at Etsy, if you don't feel like sewing and recycling yourself.)
