Tea of various kinds. Loose and bags. I drink gallons of tea.
Yarn for knitting and crochet, and fancy stitch markers, patterns and accessories.
Cross stitch and embroidery patterns and supplies. I have an embarrassing amount of thread boxes full of bobbins of embroidery thread. I love etsy for interesting patterns.
Skincare, Bath and shower stuff, makeup, perfume, general lotions and potions. I have a dressing table full of crap, and shelves above it, plus loads in the bathroom.
Those cheap fluffy soft chenille socks that are lovely and warm. I have loads of them, DD often steals them from my drawer as she's another one whose feet are always cold.
Books, I have a kindle, I got better with buying books for a while but we have a really good second hand book shop near us that I am incapable of walking past without buying a bag full of books.
Candles, they're everywhere.
Cat toys, also everywhere!
