My ratcheting tie-downs came with a little nylon bag that I use. I just roll them up and stuff them in, not normally a problem getting them back out.
My tow strap I keep in a Bucket Boss Jumper Cable Bag (actually a slightly different version, but they discontinued it, I have this one for my jumper cables).
