Here's a picture of the bed tent closed. The window is made of clear vinyl. Both outer and inner fabrics are quilting cottons. The outer one is a flowers and butterflies print. The inner one is of colorful dinosours on a blue backgroud. Two sport-weight, molded zippers close the door. Twill tape was used to edge the window.

Here's a closeup of the hardware. My husband used copper pipe around the 4 sides of the opening, and used custom-cut wood blocks to mount it. Definitely "cleaner" than my tie-down idea. I made flaps to wrap around the pipe and snap down. The gap is a bit large. Something I'd correct if I made another one.

Here's my orginal idea-drawing. As you can see, I had planned on appliqueing the tent to look like the front of a house. The flap would have been the door, with windows to either side. Plus flowerpots and plants. The little smiling stick figure was added by my 4 year old. I caught her in my sewing room!

In the end expediency won out. I decided it was more important to "just get it done" and all that applique work would have taken ages.

Here's my high-level measurement drawing. This is the one where I figured out how the thing would fit together. As you can see from the drawing I split the top and bottom edges into 3 flaps, so that we could add additional reinforcing mount blocks partway through the long span of pipes. Copper pipes are very flexible and I didn't want there to be any kind of trapping hazard if my daughter tried to slide underneath them.

After I had the design worked out I drew up a cutting diagram. I find that when working with something like this I really need to draw everything out to avoid making mistakes. That's partcularly true when I'm working on a project, like this one, over several weeks. I rarely get more than and hour or two to sew a week so designing and making this tent took quite a while. Its really easy to forget small details unless I write them down.

Lastly is my interfacing guide. This is actually just one page of three that describe how to place the interfacing. For construction I just jotted down a few notes and mostly just figured it out as I went. To join the face and backing fabric I used a method similar to the bagging mehod for lining jackets.
