Wish I could help you, but I'm pretty sure there is a way. Some of these talented quilters will know. Maybe if you searched for it on the web you could find a pattern. The last one I put on my bed was from an old skirt that kept
slipping and sliding off the bed and would just hang and look terrible so took it off and found a "bedspread" that went
all the way to the floor. Then I decided I wanted a quilt so I made one and it didn't go all the way to floor; so I retrieved the old bedskirt and cut off the ruffled part and bought some of those swirly pins and screwed it into my mattress. Worked beautiful. Good luck on your bedskirt. Know someone will come along and help you.
