I'm so envious of people that have rooms specifically for crafting. Our extra room is used for our classroom (we homeschool) so my crafting paraphrenalia is delegated to the kitchen/dining room. I thought I'd share a picture of my sewing cart organized with my most used stuff. My sewing machine is on the kitchen counter (I prefer to stand when I sew) and I pull my cart up next to me for easy access. When I move into the living room to sit by the fire and watch TV, I drag my cart in there and have all the necessities that I need. The top has several trays that hold the smaller tools, the middle holds stacks of felt, and the bottom holds stuffing, my box of embroidery thread, and baskets of wool felt scraps. The orange floral feedsack bag on the floor holds my fabric scraps.
Here's a close-up of the top level. Left to right: an assortment of glues and fusible webbing, pincushions, rulers and right angle, marking pens and pencils, various tubes and sticks for turning fabric tubes, tape, small patterns, oversized rulers, scissors and other sharp implements. Under the trays are folders of ephemera that I use in making my tags, and another tray that holds my glasses and misc.
The green cabinet behind the cart is full of more sewing/crafting stuff. I'll share a picture of that tomorrow.
