We live in a stupidly tiny flat. Me and 2 young adult DC. I have regular clear outs to the charity shop, there's just no room for too much stuff.
Hairdryer, I have 4 shelves on the wall above my dressing table that have things like that, products, straighteners, rollers etc, plus knitting, crochet and cross stitch stuff in storage boxes.
Hoover, I have a shark and it lives in my bedroom, tucked behind the curtain in the corner so it's not visible.
Christmas decorations go in storage boxes, some in the airing cupboard, some on top of my wardrobe.
Spare towels on wall shelf/rack thing in the bathroom. Bed linen for all of us in a drawer in my divan bed. Summer/winter duvets vac packed in the other drawer.
Coats, we have a coat rack on the wall by the front door. Summer coats gets vacuum packed and put in the airing cupboard in the winter and vice versa. Same with clothes but those go on top of the wardrobe.
