I'm entering this in the Sew Useful contest because it's useful not only to beautify your tv but also to promote marital harmony. I think a husband (or wife) considering getting a flat screen against the wishes of their spouse should consider investing in this TV cover. After all, what's $30 when you're spending thousands on a tv?
The tv cover pictured fits a 40 inch Sony Bravia and is for sale at my etsy shop here: http://www.etsy.com/view_listing.php?listing_id=6393753 .
Step 1: Gather materials
Flat screen tv (wall mounted works great)
A piece of canvas or duck cloth (something sturdy) as large as your tv
Heavyweight fusible interfacing--large enough piece to cover the front of your tv (optional)
Fabric scraps to make your design
Fusible webbing (different from interfacing, this is "sticky" on both sides when ironed--Heat'n'Bond is an excellent brand for this project)
Approximately 1 yard of cotton fabric for edges (depends on the size of your tv)
Enough 1/4 inch elastic to wrap around the perimeter of your tv
Step 2: Measure and cut
Carefully cut your piece of duck cloth to this dimension making certain it is square.
If desired to add stiffness, iron the heavyweight fusible interfacing to the back piecing as needed to make a single thickness layer.
