I'm a firm believer in bed-skirts, just as pillows they but a finishing touch on a made-up bed. Especially in any room where you store things under a bed, like a childs room for instance. I store all kinds of items under my kid's beds, not to mention what ever they decide to store under there themselves. They are so easy to make and very inexpensive.
You Will Need
Fabric for top (I use an old sheet)
Fabric for Drop (I used the flat sheet that matches the fitted sheet on the bed. I never use the top sheet when making the bed anyway)
Measure the size of the boxspring you are covering and the drop (distance from top of boxspring to floor) For a twin sized, which is what I did, my measurements were 75x38 for the top and a 10" drop. Note: the size of my drop is significantly lower than if you have a traditional boxspring. I am using a "bunk-buddy" boxspring, which is only 2-3 inches thick.
Note: when I cut my sheets to make the drop I make sure I cut them with the hemmed egdes at the bottom of the drop. This saves a lot of time not having to hem the bottoms. ☺
Sew with right sides facing together, first sew the foot end, then one long side, then the other. When sewing the long sides start at the head of the skirt and work your way down to the foot, when you get to the foot end sew the remainder of the long edges underneath the foot drop to hide the end.
