How well does canvas stick to canvas and how well does canvas stick to foam??? I ask because I'm wondering if pre covering panels and ceiling with canvas before painting will hold together. I don't want seams to show thru paint...and how do you blend the seams so they don't show??? .looking at building a low (three to three and a half) high x six foot by four wide just for sleeping in.
Any thoughts?

canvas sticks very well to canvas.
i am also leaning towards the pre-covered panels. but as far as i can tell, this has not been done yet. so i don't have any personal knowledge. i do know from my own experiences though that my canvas pieces that attach to canvas are just not coming up. i do know that just a piece of canvas laying on foam can be pulled off. but it will not be pulled off if ends are attached to other ends. like in a complete wrap (canvas to canvas). my canvas on my foamie is wrapped, its wrapped around the doors/ windows, and underneath the floor (where it is also stapled down). but i have tried to a certain point to peel it off and its just not going to happen.

as far as seams go, i don't see how to avoid that without putting a decorative edge on, which can be done.

A fast comment:

It's been mentioned elsewhere here in the foamy section -
I don't have time to look for it at the moment - that if you're
planning to try to precoat the foam panels with canvas and glue a/o
paint that you should do it to BOTH sides of the foam 'at the same
time/session', otherwise there is a big probability that the drying
canvas and its coating will warp the foam panel if it is only applied
to one side and allowed to dry out at a time. And also leave enough
canvas free at the edges to have a good overlap to the panels you
will connect them to in assembly.

Cheers,
Norm/mezmo

Norm, that was a problem Mike was having. It's in either his build thread or mine.
As for hiding seams...
I'm using epoxy and glass but it ought to work for canvas as well:
if you sand down the foam along the seam to the width of the lap in the joint and the thickness of one layer of canvas, your lapped seam won't be proud of the surface.
Your 'hide' wil go from a big noticeable seam to a fine line that can be filled and sanded. A pic is worth a bunch of words - I think they're in my build thread as well. I'm on my phone now, I'll edit in a pic when I get home.

I had the same thoughts while building the Road Foamie. I used fiberglass outside and thin ply to cover my foam panels on the inside. Then I assembled. I reinforced the mating edges with fiberglass tape and epoxy. I then capped the edges with 1/2" thick foam pre covered with canvas. That hid the seams and gave a "designer" look to the thing. I even highlighted them by painting it a contrasting color. Joining the panels, creating a composite panel with the fiberglass and thin ply, taping the seams, attaching them to interior bulkheads and capping the joints has created one very strong structure. I would do the same again if I were to do it again. Canvas or fiberglass, I'd do the same thing.
