I LOVE WOOL BATTS- THE HOBBS AND THE DREAM WOOL!!! they are wonderful to quilt, drape beautifully- are lightweight- fluffy-cozy---FABULOUS!!! if i could afford to i would always use wool batts- but since they are (top shelf) i save them for special quilts. the quilt that lives on my bed has a wool batt in it- it gets tossed into the washer & dryer every now & then- been washed/dried probably half a dozen times- i love hugging that quilt fresh out of the dryer! it is so fluffy & soft!!! and they do not shrink like cotton batts... i dry mine in a regular setting dryer.
