Giving favorite images the custom treatment doesn't require an expensive trip to a frame shop. A few simple steps paired with readily available supplies can transform precut window mats into elegant showpieces worthy of their contents.

Mats adorned with delicately outlined borders, graphic photocopy transfers, and decorative paper are all amateur-friendly projects. Combined with classic framing techniques, the final results look purely professional.

Ink and Pencil Mats
Mats rimmed with contrasting borders and lines give a polished look to black-and-white photos. You'll need a mat (preferably archival quality); a clear plastic ruler; India ink or black, white, or colored pencils; drafting tape; gouache or metallic inks; a watercolor brush; and a pen and nibs (if using ink).

1. To create a painted inner border for the window mat, use the ruler and a pencil to mark outer edges of the area to be colored. Apply strips of tape along drawn lines.

2. If using gouache, dilute a dab with water in a small bowl, mixing to the consistency of cream; metallic inks can be used without diluting. Apply gouache or ink with brush. Let dry before gently removing tape.

3. For additional borders, use ruler and pencil to draw guidelines. Trace lines with India ink or a pencil. For crisp lines, keep ink nibs clean and pencil points sharp as you work.

4. Add shaded borders if desired by filling in between lightly drawn guidelines with pencil strokes.
