Get a short piece of 2x4 about 12" long or so, glue or screw a piece of 1/4" plywood 3" wide and the same length on the bottom to form an upside down "T". Now drill some 3/8" holes along the length of the top edge of the 2x4 to hold your blades vertical. Leave enough room around the holes to write the blade size that goes in the hole. You can sit it on a table or shelf within easy reach of the saw.
WARNING! You may have to empty it of blades and dump the sawdust out of the holes every year or so.
Also keep a covered coffee can near by to put broken, burnt up, worn out blades in. It will hold a TON of blades (well not literally) and can be taken to a recycle center in a few years. Please don't just put blades in the trash where someone can get cut, poked or stabbed with those sharp little suckers.
