I bought a small rectangular magnet about 1" wide, 1/4" thick and 3" long at Home Depot. It sticks to the face plate of the sewing machine, up tight against the presser foot and guides fabric right through the machine for perfect 1/4" seams. It also provides a place to stash pins as you remove them during sewing and picks up spilled pins all at once in a nano-second.
Hormel, Tyson and other brands of microwaveable beef tips, pot roast, etc. come in small plastic containers that are great for everything from needles to bobbins, scissors, seam rippers, pins, whatever. They're flat and rectangular and don't damage anything.
Two-gallon re-sealable plastic bags are great to store projects you will, one hopes. soon finish---you can see them and store pattern, fabrics, notions needed, etc. all in one place, ready to go when you are.
Foam-core poster board cuts easily with a box cutter, can usually be found at Dollar Stores and makes great core boards for wrapping long lengths of fabric just as the stores do but using less space than the 1/2" thick cardboard wrapping cores used in fabric stores.
I use a rectangular basket for small patterns and use a hanging sweater bag with five or six slots for freezer paper, fusible papers, template paper, bags of trim, projects waiting to be done, etc.
