A simple wire rack dries things easily if you have floor air vents. I machine wash my slippers (Wal-Mart), and this rack dries them quickly while retaining their shape. Since I wear the slippers for hours each day during cold weather, I also put them on the rack every night between washings. Keeps them fresh as a daisy, and I know where to find them. See my related Instructables, including a glove dryer for an overhead air vent, click on "unclesam" just below the title above or in the INFO box to the right. On the new page that appears, repeatedly click "NEXT" to see all of them.
Step 1: Materials and Tools
Two heavy wire coat hangers, of color to suit your decor
Pair of combination pliers having wire cutter
Screwdriver, flat blade
Floor air vent cover, pulled from duct where rack will be used
Step 2: Cut Off Hanger Hook
Remove the hanger's hook, leaving all the untwisted wire.
Step 3: Form the Loop
Straighten the hanger's elbows. Form a wide loop exactly at the middle of the wire by wrapping it partway around something round. Size the loop to fit your footwear. Something 3 and one quarter inches diameter creates a loop that fits in my male U.S. size 8 slippers.
Step 4: Size Does Matter
You know what they say about men who have big feet. That's right, it means they have big slippers. Push the loop up into the toe of a slipper or shoe and mark each leg of the loop about an inch and one half beyond the heel of the slipper. Remove the loop and bend each leg outward at the mark.
Step 5: Bend the Legs Up
Bend each leg to parallel its side of the loop.
Step 6: Form Tabs
Bend each leg out of the plane of the large loop to form a short tab about three eighths of an inch long. The tab should not be so long that it will interfere with operation of the movable vanes in the vent cover.
