Too much to tell my DP about. I tend to hide it, or he wouldn't be impressed that I have stuff I don't 'need'.
I have bought some especially for projects, and then I see something on offer, or is irresistible...
I have 2 large bags of wool, needles and knitting accessories in my wardrobe, and bits and bobs in my dresser drawer, and more bits and bobs in the sideboard. The idea being that I have projects I can pick up when I feel like it.
I have a small tool box of general crafting supplies, like stickers, paint, glue, glitter, etc
I have a large tool box for my sewing stuff like needles, etc, and a small storage box for fabric scraps, buttons and ribbons, and two large storage boxes of fabric.
I also have 3 storage boxes full of silicone bakeware. But I subscribed to a magazine which has nearly finished, and most of it had been really handy!
