Take a large size sewing needle, large enough to handle some heavy thread. I found some in my wife's sewing basket.

Thread each morel through the base of the stem (just like stringing popcorn for the Christmas tree) and hang them upside down in the garage. Tie the two ends of the thread as far apart as necessary to insure that the morels do not touch each other. The tighter you stretch the thread the easier it will be to keep them from touching together. Now just let them hang there and dry out.
