I had an older store bought bed skirt that I loved. Now that I have a regular double bed I can use it again. I took it apart from the muslin that went under the mattress. I serged the top edge then used T pins - upholstery pins - and pinned it on. It's been on for not quite a year without any problems at all. [Believe me I was worried I would have to go the velcro route.]
