Anne,
I am not sure what you are trying to build but the below photo shows if you have a desire - you are 90% up to the task. My wife couldn't find the trellis she wanted and the ones she did look at were too expensive for what she was willing to pay. She sat down - drew up what she wanted - and built it herself!

There are tools you will need to own or borrow though - not a difficult task - many neighbors would be willing to help - I am sure. She used a table saw, chop saw and pneumatic stable gun. She attached the trellis to the house with 3 1/2" galvanized screws (4 per trellis - 2 spaced on each side) using a 1/2" copper pipe coupler as the spacer. Good luck!

Hudson WY, Those are great, your wife did a wonderful job. I probably didn't explain it very well, but the "trellis" like structure I'm talking about would look more like an awning over an outside window. It would only be at the top of the window. 2 brackets (wooden shelf type brackets, but larger) on either side of the window and then a few (3) lathes strips connecting the brackets. sturdy enough to support the wisteria growing over my window. The plant is already up the wall of my house and trying to cover up my window and I am trying to train it to grow over the window and up and over the side door overhang. I am having trouble describing it without a picture.

Try googling with the words arbor over garage or pergola over garage +instructions.
