Hanging traditional window treatments often means getting permission from your landlord if you're a renter, as well as fumbling with a drill and defacing the walls or trim with screw holes. A few of today's options, however, don't even require tools or destructive fasteners, allowing more decor freedom -- in a rental or in your own home.

Ready-to-Hang Rods

Your window trim's upper corners are ideal for hanging a curtain rod when you use specialty ready-to-hang rod clips. Each right and left angular clip slips over the trim, grabbing it from behind. The clip fronts have slots for standard curtain-rod hardware, so they take the place of their wall-mounted counterparts.

The trim clip application is handy for shallow windows where inside-mounted window treatments aren't an option. On small windows, however, narrowly mounted curtains cover much of the glass, reducing natural light and restricting the view, compared to hardware that mounts farther out for stacked back panels.

Peel-and-Stick Blinds

Stop trim "abuse" by using peel-and-stick blinds. Typically, these cut-to-size window treatments are as easy to install as they sound:

  1. Peel off the tape's protective strip.
  2. Adhere the blind inside the window frame or along the upper trim, as desired.

Tension Rods

Some blinds have spring-loaded rods that wedge between the two sides of the window's frame. For more design freedom, however, you can simply use an appropriate-sized tension rod -- similar to a spring-loaded shower-curtain rod -- on which to drape a window scarf. Fit it with traditional curtain rings, clips or hooks for standard drapery, or hang tab-top, tie-top or grommet-style curtains.

Hooked-and-Loop Tape

Hook-and-loop tape comes in peel-and-stick and stitch-on options, and either kind works for hanging curtains without conventional hardware and screws. Apply one piece of tape to the back of the curtain and its mate to the upper trim or wall above. Although you can't stack the curtain panels, you can pull them back and expose the glass using tiebacks -- also mounted to the wall or trim with Velcro.

Magnetic Fix

In some cases, such as with a metal window casing or a metal door with a window, a magnetic window treatment is useful. A magnetic curtain rod is designed to hold fast on a metal surface, negating the need for screws, and comes in finishes such as brushed nickle, bronze and iron. Magnetic blinds come in white, black, wood tones and various other standard finishes.
