I also have more than one set of notions. I keep them seprate in sewing boxes, or baskets, so when I want to take a project someplace or just go to the living room to work on something while watching T.V. I have everything on hand. I do not duplicate my special rulers but do have some small ones like the 6 inch, I have a box each for embroidrey, applique, english paper piecing, crochet, general mending and sewing, 2 boxes for embellishments ( 1 is just for all the beads, an speciality items), and my class supplies that always stay in my case. Then there is my everyday quilting notions, each box also contains pins needles pincushion ect. things that are not special to the project but needed. Over the years I have slowly made these boxes so the expence has been spread out over time, it is sure nice to decide to do some applique and just pick up the fabric and one sewing basket and have everything I need instead of having to dig into my class box or run all over my sewing area to gather everything up before I can start. Oh Ya! these are good size boxes, I can store my project in with the supplies if needed.
