My sewing machine and I are in a fight, so I made this bedskirt for my/my brother's/the guest bed at my mom's house without any sewing.
This is how the bed used to look.
To make the no-sew bedskirt I used these supplies; a tablecloth (or if you don't have an extra tablecloth hanging around, a flat bed sheet or three yards of fabric would work), clear packing tape, iron-on adhesive, scissors, measuring tape, and an iron.
The bed is a full. For the skirt I cut out three panels, making sure to align the long sides with the tablecloth hem. See the diagram below for my exact panel sizes.
I used iron-on adhesive to hem the left and right (short) sides of each panel. The bottom (long) side didn't need to be hemmed because it incorporated the original tablecloth hem.
I used packing tape to attach the panels to the box-spring. The key is to overlap the fabric up onto the box-spring at least six to eight inches - this way the weight of the mattress will help hold the bedskirt panels in place.
I folded the top of the corners under like a present. Even though it will mostly be covered by the mattress, the top of the corners is likely to show a little if the mattress shifts.
Here's a close-up of the finished bedskirt. (I swear it's not so wrinkly-looking in real life).
This was an easy project, and it has held up perfectly so far - I actually made this bedskirt three weeks ago. Take that sewing machine!
