Why not use the coffee cans to hold binding? I have been using small cosmetic bags to hold binding "kits" (i.e. needle, needle holder, scissors, threader). I saw a suggestion to use the flat curtain rods to help with the side tension for the LA>
I also use baggies for holding cut pieces for my blocks. I have jelly and sorbet jars to hold my pins and wonder clips. I put bobbins in some old candy boxes. Scharffenberger factory was near where I used to live and they sold the little squares in these nice boxes with latches.
