Bulb storage after growing indoors

How can I store bulbs that have been grown indoors so that I can plant them in the garden for next year?

Doug says - why store them? Plant them outside right now. They need to grow and develop leaves so those leaves will produce stronger bulbs. Outside is perfect now if no more deep freezing temperatures or right after the last frost if in very cold climate.

Frankly, without proper storage facilities you won't keep them alive for an entire year. Plant outdoors now.
