Depending on how much you have, you could make a wall hanging, that would really display the old wool. May I suggest that you go thru every piece and make sure the wonderful bugs have not had breakfast, lunch and dinner on the wool...would be horrible to start and not be able to finish. My most favorate pattern is the log cabin, and would be my first choice, second would be a diagonal strip. If you have tons and tons then make a quilt. i would recommend you wash before unless you are making just a wall hanging. If the strips are from old clothing, then you know they have been washed before. If not do some test pieces, see what happens with cold water...see what happens with hot, that would be like felting it, really tighting up the weave, my only worry would be the age and if it would survive....IMHO
